Summary Like many others I jumped ship from the iPhone when the 4S was released. I loved my iPhone but was disappointed with the lack of a larger screen and same old form-factor. I also grew tired of living in Apple's ecosystem; being tied down to 'their' way of doing things. They make really great products but for me it was time to branch out. I picked up the Skyrocket in early November. Here are my thoughts after using it for nearly two months.
Beautiful and bright screen. One of the best I've seen. Colors are rich and vibrant compared to most other phones I've seen. The large 4.5" screen makes one handed typing difficult but the tradeoff is completely worth it. Games, movies, and web browsing is amazing. It makes it painful to go back to the iPhone.
4G LTE. The difference is night and day compared to 3G. If you have an unlimited data plan this phone is worth getting just for LTE.
Extremely fast dual-core processor. Apps load insanely fast. I've heard some people complain of lag due to the snapdragon CPU but I have not seen any issues myself.
Great camera. Not the best ever (iPhone 4S is better) but it doesn't disappoint. It's one of the best cameras you will find on an Android phone. I've heard people say it's better than the Galaxy Nexus, too.
Google apps. Maps, Gmail, Talk, Voice search, etc. They work well and are better than what you get on iPhone. Maps has more features than what is available on iPhone like Labs, turn-by-turn voice navigation, and walking paths, for example. Voice search is as great as Siri on iPhone 4S, minus the gimmicks.
Battery life is decent. I can easily get a full day on one charge. Granted I used to get two full days on an iPhone but for an Android phone one day is great. Keep in mind android phones are generally more powerful, are able to run background apps, and have faster cellular antennas (4G LTE) which drains battery quickly.
Upgradable to ICS (Ice Cream Sandwich). Samsung has confirmed this phone will get ICS. Some say Q1 2012, I wouldn't expect it earlier than late spring/early summer. But honestly this phone is great even without ICS.
Light weight. Some say light weight phones feel cheap, and they may be right, but ultimately I want my phone to be light and easy to hold for long periods of time (for reading, watching movies, games, etc)
Customization and power of Android. Coming from iPhone this is simply refreshing. You can totally change the look and feel of everything so it suites your needs perfectly. All stock apps can be replaced with better downloadable apps (Email, Gallery, Camera, File Browser, etc) which you could never do on an iPhone. For example I replaced the stock Email app with the Touchdown which has superb Exchange support. Don't like the default keyboard? You can choose from dozens of other keyboards to download and use. (the default keyboard is actually pretty good though).
Samsung/Touchwiz interface. Admittedly I actually like Touchwiz (at least better than any other manufacturer skin) but this added layer is largely unnecessary, especially with Ice Cream Sandwich coming soon. Some parts also look too much like iPhone/iOS, like the text message app, for example.
Screen is not HD. The pixel density of the screen is not on par with the Galaxy Nexus, HTC Vivid, or iPhone 4. While it's difficult to make out the pixels, I would have hoped Samsung would have used a higher density screen for a top-of-the-line phone.
Plastic body. This is completely a matter of taste but I don't prefer the plastic body of this phone. I was used to the glass and aluminum of the iPhone 4. It's not a deal breaker though, especially if you use a case. And the upside is that the phone is really light weight.
Web Browser could be better. The iPhone web browser is generally faster and displays content more consistently. It also has a weird quirk where all your tabs will close a few minutes after you stop using it. I would prefer the browser maintain my open tabs all the time, even between reboots. If someone finds a way around this let me know! Anyway, I use Dolphin browser which is a fantastic alternative.
If you are like me and have used an iPhone for years I don't think you'd be disappointed. The large screen, 4G LTE, camera, and performance you get from this phone make it a great all-around package. Alongside the Galaxy Nexus I believe this is one of the best Android phones you can buy right now.

Pros -Excellent Battery life for an LTE-enabled phone
-Blazing-fast LTE speeds (55Mbps down!!!)
-Super AMOLED Plus screen is great
-Mobile Wi-Fi tethering included
-8MP camera takes great pictures
Cons -NFC (Near-Field Communication, for Google Wallet, etc.) is included, but is disabled for some reason
-No LTE on/off switch for saving battery, but the included battery is more than adequate to last the whole day
Summary Have owned BlackBerry phones for most of my life (8800, 9000, 9700)but was so disappointed by the Torch 9800 that I finally ditched it for a Galaxy S Captivate, which was my first taste of Android OS. My contract was up and the choice for me was between the Samsung Infuse (the non-LTE Galaxy S II that ATT sells), the HTC Vivid, and the Skyrocket. I live in Atlanta so I wanted to take advantage of the LTE capabilities offered here. I ended up choosing the Skyrocket because of its far superior battery life than the Vivid, and I can say that this is the best phone I have ever owned. Absolutely blows the iPhone 4S out of the water (and I own a MacBook Pro and iPad2, so I am an Apple fanboy). $250 might sound a little steep but the extra $50 over the other two models is absolutely worth it. TouchWiz isn't the battery hog that Sense is, and if you don't like it then just use LauncherPro. The phone's responsiveness is blazingly fast, and the speeds achieved by LTE and even HSPA+ are fantastic. As far as reception goes, this is really the first ATT phone I've owned that i can consistently say has excellent reception. I was in the GA Dome for the Falcons game Saturday, and my friends with iPhones and the like had no service while I was happily zooming along with 4-5 bars of LTE. Even if you currently don't live in an area with LTE capability, H+ works just fine as well. Additionally, ATT has promised an update to Ice Cream Sandwich (Android 4.0) after Xmas.EDIT: I gave the phone 4.5 stars because obviously no phone is perfect, and the disabling of NFC and the lack of an LTE on-off switch do detract slightly from a perfect score imo. But the Skyrocket still is the phone to beat among ATT's offerings :)
Additionally, ATT's LTE network is STOOPID fast. I was achieving speeds of 55Mbps down at one point in the GA Dome. Speeds will drop off some as more LTE users come onto the network, but it still puts it well above Verizon's LTE speeds.
The 8MP shooter included in the Skyrocket takes exceptional pictures. Predictably, low-light shots suffer some minor saturation issues but otherwise the camera is very good and would be more than adequate for taking pictures on a regular basis.
In short, you honestly will be doing yourself a disservice if you don't buy this phone. Samsung has come through with a clear winner and I promise you won't regret your purchase.

Pros Brilliant screen, Better screen size, fast fast fast, runs my business software flawlessly, video at 1080P fantastic. The hot spot tethering is a HUGE hit with my customers.
Cons Like all smart phones battery life has to be properly managed, about the same as my iPhone4
Summary So far the best phone investment I have ever made and I have purchased about 50 phones in the past, including windows phones, push to talk phones, many iPhones and now my first but not last Android
Pros Big screen, freedom to configure, 4G/LTE phone, updatable to ICS soon.
Cons Bad camera, quality's just isn't there.
Summary Love the big, bright screen. I bought my Skyrocket about three weeks ago. I switched from an Iphone 3GS because I wanted a bigger screen to better read my emails and view web pages on the go. It took me a week to adjust to Andriod's UI. Although the Skyrocket is very nice and easy to configure, on occasions it's still taking a few more steps to do certain things compared to the Iphone. Now that I'm pretty familiar with the UI, I may not ever go back to Apple. I like the fact that I don't have to depend on Itunes to update my phone. I could just plug in the enclosed USB cable and drag and drop music files. As nice as the Skyrocket is, it's not perfect; I hate the fact that the volume rocker and on/off switch were at the sides instead of at the top because I usually press one or the other by mistake. Other reviewers complaint about battery life but if you switch if off (not turned off) when not in use, the batter tends to last longer. Other people also complaint about the lack of software but that's not my problem. I mainly use my phone for calls, emails, listening to music, and do a brief web search when I'm out. The only game I have on my phone so far is Angry bird; I also have my real estate icons such as MLS, Realtor, Zillow, and loan calculators. The camera takes great pictures if you have adequate lighting. If it's low light, your pictures turn bluish in color. This week, a reddish spot appears in the middle of my camera. When I took pictures, the the red spot was captured as well. I took my phone to my local ATT store to swap a new one but there were all sold out and was told to come back when the next shipment's arrive. Despite the problems mentioned, I intend to keep my phone except the exchange I intend to do. I wanted the Galaxy Nexus but don't want to switch to Verizon since they don't have roll over minutes like ATT. Besides, the features reviewed on the Nexus isn't that great either that's why I bought the Skyrocket now. I believe the Skyrocket is the best smart phone out there todate. You won't regret buying it.
Pros So many pros, the screen is great, battery life is decent not horrible, I read some people say it feels cheap but I'm glad it feels like plastic because it is SUPER light and super thin and very durable.
Cons The only con is that it burns thru data like water but I'm a heavy user and once I get my kids their tablets it might be better since they won't be on my phone all the time.
Summary You will not be dissappointed with this phone.. I held it side by side with my colleagues iphone 4s and his phone looked ancient and moved very slow compared to this.
