The Design of the Nexus One
The Nexus One is by far the sleekest looking phone that HTC has put out to date. It is similar in shape to its predecessor the MyTouch, but much more elegant. There are less buttons on the front, and a very nice looking two-tone color scheme. The lighter color wraps around near the middle of the back and is engravable when you order the phone. The darker color actually has a nice rubbery feel to it to for better grip (Woohoo less "dropped calls").
As far as the front of the phone goes, there are five basic inputs or six if you count the touchscreen. There are four haptic buttons along the bottom of the screen and the track ball below that. The buttons are for quick access to the home screen, to go back, to open up the menu or to do a quick search. The track ball probably won't get used as much as it could, but thats because of the seamlessness of the touch experience on the Nexus One. Basically the trackball will be used for your notifications, you can change the color for different notifications, and for playing games. Other than that it isn't really needed. The 3.7 inch widescreen WVGA AMOLED touchscreen supports an amazing resolution of 800 x 480 pixels.
Around the edge of Google's Nexus there are the standard volume control buttons, the power button, a 3.5 mm headphone jack and another LED to let you know if the phone is charging and for notifications as well.
All in all, this is a great looking phone that has the grace that the Motorola Droid lacks, as well as being slimmer than it, and the muscle under the beauty to make it superb.
