Pros Beautiful, simple and easy-to-learn functionality
Cons Certain things require a G5
Summary It's the best OS available, and it requires the best hardware available. No problems there. The only problem I've found is that the new HD codec (H.264) only works on certain G5 computers, not on my 1.67 GHz G4 PowerBook, even with the added RAM and upgraded GPU. In the four years now that I'v been using Macs, I have never experienced a crash, a virus, or even the slightest freeze. Like Apple says, "It just works."
Pros EVERYTHING! SPOTLIGHT, QUICKTIME, ITUNES, YOU NAME IT!
Cons if this thing has cons, why would i bother rating it?
Summary This is the best OS I have ever used. I got my first mac, a mac mini, on 4/29 when tiger came out. the mac mini is the cheapest one you can get, the 1.25 GHz base model. Tiger works smoothly on this miniscule mac with meager allotments of ram (256 MB). This OS provides a more interactive interface than WINXP (which is crap). The dock and widgets are cool, and spotlight is integrated with the finder bar, which makes it easier to search for something. I plan to upgrade the hard drive and memory to make Tiger work as smoothly as possible. I tried to open the mac mini, but to no avail. If you have a good tip as to where to insert the blade to pop the mini open, please comment** thanx
Pros Lives up to the hype and is noticeably faster than 10.3 on a G4
Cons Partially broken (for now) Virtual PC, occasional blank Inbox in Mail.app
Summary As a recent convert from Windows, I viewed Tiger's claims of "better performance" on older hardware with a high degree of skepticism (see: any Windows upgrade).
Forgive my ignorance, old habits die hard.
My girlfriend immediately noticed that everything was faster on my 12" Powerbook G4 without having to tell her I had upgraded the OS.
The widgets in Dashboard (especially the weather and phone book) are nice, but I still mourn the loss of Sherlock (or Karelia's Watson). As more widgets become available, I'll get used to Dashboard.
Mail seems to be much more polished and the Exchange setup is easier, though setting it up to use Exchange/AD to get the addressing auto-completion was a 2-day fight. The fix was to point LDAP to my domain controller's Global Catalog at TCP/3268 instead of Exchange's LDAP at TCP/389. I have a bug where my Inbox root folder will go blank on occasion (no set pattern) requiring me to close and reopen Mail to refresh the content.
Safari is faster and the RSS features are nice, but I'm not sold because it's still unusable with some of my key web-based apps (work-related), Firefox shares a similar browser id string (Mozilla-based, etc.) so I'm not sure why Safari doesn't work with those apps if Firefox does. So, I choose to use Opera 8 instead because it seems to be faster than either Firefox or Safari.
My biggest gripe is that Tiger broke the virtual switch for Virtual PC 7 for Mac. It also absolutely dogs the client OS (Windows 2000) almost to the point of unusability right now. I expect a fix soon, but this shouldn't have happened in the first place. Virtual PC for Mac isn't exactly a rare/obscure application.
All in all, Tiger is a worthwhile upgrade based on the performance improvements alone. The eye-candy (Dashboard, Safari, etc. ) and improving connectivity with Active Directory is all gravy.
Pros Several key features that add real value to home user
Cons Doesn't run on Intel/AMD architecture
Summary This is no Panther upgrade. Spotlight, Dashboard, Automator, Safari RSS...all these features significantly increase the value of a home PC by making getting email, working with files, surfing the web, etc. simpler, faster and more elegant than with previous Mac OS releases. (Certainly more than the alternatives.) I think the only downfall of this release is that people with PC's will to wait 18+ months for similar features with Longhorn.
Pros Not Sure??
Cons Probably the cost to upgrade, otherwise not known yet.
Summary I AM A SWITCHER!!! I have been a PC Loyalist for many years, and I have become a MacHead. There is a reason for everything they do. This upgrade will add very usefull tools like spotlight. If spotlight is integratged into the system properly, which it probably is knowing apple, then it may just save you seconds when they really count the most. Like during a business phone call, when you need that one piece of information from excel but you just cant remember where it is exactly. You can just type in as much as you can remember and it will give you what you need. Im hoping this will be an upgrade worthy of the cost because im not used to this in the windows world. But judging by how well OS X 10.3.8 (A.K.A. Panther) works then OS X 10.4.? should be worth the price.
