Android was designed from the beginning to operate well as a touchscreen operating system. Like the HTC Magic and many other Android-powered models, the Nexus One is a powerful touch device.

It's easy to swipe through photos in the Gallery app, long-press on emails and click to start apps. The 800x480 pixels screen is bright and clear at a 100,000:1 contrast ratio and mostly operates quickly - faster than the HTC Magic and Milestone.

The main issue here is that it is not always perfectly consistent. The touchscreen is usually smooth, but there were times when the phone did not register an input or there was a slight pause.

Also, the touchscreen does not respond to gestures - it's not multi-touch (in the US, although we're hoping it might be in the UK), so you can can't zoom in elegantly on the screen (although you can press to zoom in).
