What to improve in linux for my PDA (iPaq h5450) (what WinCE does better)

 * Fast wake-up
 * Ability to detect cradle/charger without waking-up
 * Using more colors on the charger led
 * Fast scrolling (no flicker)
 * Only 4-way cursor button (no false button presses - better debouncing?)
 * Wake on any buttor (calendar, ...) (can't this be dangerous?)
 * Text recognition only when needed - automatically gets off the way (not a problem with xstroke?)
