The Xda Exec is a clamshell device. Open it up and you have a mini laptop,
with 3.8in screen at 640 x 480 pixels. The screen is bright and clear
and the extra pixels really help. Sadly there are only 65,000 colours,
but this is not really a problem. Beneath sits the keyboard with full
qwerty key layout, a number row, and above this a half-height double-
width row of shortcut keys. The shortcut keys let you start and end voice
calls, start a video call and jump to your contacts.
