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?)
