Conclusion
Samsung has released a slew of slider phones in the past year or two. The Ultra Edition 12.9, aka D900, is the current king of the hill. With its impossible slim profile and sleek black styling, the D900 is one of the chicest handsets I've ever tested. The fact that it's adorned with just about the best display you'll see on any mobile phone these days makes the picture all the prettier.
Samsung also packed the D900 with a host of features worthy of top-of-the-line status, including a state-of-the-art 262K color display, 3 megapixel camera with video recording capabilities, music player featuring an integrated digital amp and stereo over Bluetooth, and comprehensive data capabilities including Web, email, messaging, and a document viewer. The result is a phone that's almost perfect. Almost, but not quite.
If Samsung could figure out a way to pack at least 50% more battery life into the D900 without making it any thicker, I'd be hard-pressed to find much fault with this ultra slider. As it is, I really enjoyed using the phone in the mornings when the battery was fully charged. Come evening when I took the D900 out on the town, it let me down with too many "Battery Low!" warnings when I tried to use the camera or music player. As such, the D900 is a really good-looking phone that wants to do more than it often can
