Summary: I spent a little over a year looking at Operating Systems and different manufacturers, and Windows Phones metro UI and live tiles just won me over. This is by far the best Windows Phone on the market. Just a seamless, lag-free experience from the get go. The "S" has been easy to learn and use. Great reception, great call quality. The speakerphone is only fair, a lot of distortion at loud volume settings.
I love the feel of the device, even if it is a plastic build. It has a decent weight, and you will not find any actual reports of Samsung products not being durable. The textured back gives a great grip, and the button layout is logical. I have taken many a picture of my floors and inside my pockets due to the physical camera button, but now that I have had one, I wouldn't want to be without one.
The screen is just alive with color- the tiles just explode off the screen. A strange quirk is the fact a lot of the screens still do not work in landscape. I am not a fan of the auto-response on the screen brightness. Just switch it to medium. The on screen keyboards are roomy and responsive, and the predictive text is great for horrid spellers like me.
The camera is good, but will not be a major selling point. better in bright light and not many editing options. The Flash washes out details and colors in dark settings.
Multimedia is fantastic- just remember there is no Flash Player and only about 14 GB of true memory. This may be a problem for someone with a lot of music files or stored media such as books and movies. You can erase any preloaded apps and bloatware, which is great. Battery life 8-10 hours of heavy use.
Microsoft will support this phone, updates will be sent quickly and without any problems. When more features are added, you will get them. I have enjoyed every moment with my "S". I cannot recommend it more highly!!!
