While the T-Mobile G1 was a great device to start off Android with, it lacked the overall usability that the iPhone has. This phone, or really, "device" is far and away a better experience. I say "device" because at this point, "phone" is far from accurate. This isn't your grandmothers rotary-dial after all. This is a communication power house!
Multitasking is a breeze, something iPhone users don't realize they wish they had. The 1Ghz SnapDragon CPU/GPU seems to do the trick most of the time. Only when you have many apps utilizing the data connection simultaneously does it start to sputter.
The Live Backgrounds don't seem to hurt the CPU usage too much and are quite lovely to have. Widgets and pull-down notifications are what really set this device apart from iPhones.
The only area this device falters is media. Of course it does a fantastic job of playing back DRM-Free music and Videos, but those of you with a large iTunes or (in my case) Zune video collection will be writhing at how aggravating it is to not be able to play them on the gorgeous Hi-Res OLED screen. Once Google enters the Media market full force with partnerships I say it's all over.

Overall, this device is aimed at semi-tech-savvy power users. Not difficult in any way to use, but you won't appreciate it's full potential unless you're willing to do some exploring.
