- good battery life,
- screen visibility in daylight and night
- easy to use qwerty keyboard
- portablity (carried in a case work on the hip)
- no boot-up time once running
- hardy enough to withstand the dusty conditions of the Australian outdoors.
in comparison to the 5mx, a Zaurus has -
- 2-8hr battery life ( 2hr with wifi and backlight at max, 8hr if HD is spun down, and
backlight is minimal) and needs a proprietary Li Poly battery pack
- Screen is useable (but faint) outdoors in cloudy weather, or with indirect light;
unuseable in direct sunlight. Indoors its much, much brighter and clearer
than the psion
- Keyboard is very useable, but small (5mx is the best handheld keyboard
I've ever seen - you won't find one comparable anywhere)
- Smaller, but weighs about the same
- takes some time to boot; but hardly any battery drain when just suspended
so you can just put it to sleep most of the time when not needed
- (IMO) it feels a bit chunkier, and more fragile. My 5mx seemed well-nigh
indestructable; OTOH, the 5mx case cracked, but the Zaurus' is intact.
Despite these caveats, the Zaurus is a more than worthy successor.
You'll notice the screen is *far* better, if a little smaller; overall everything works faster.
I miss the stylus, keyboard, and AA batteries (all of them unique to the Psion, afaik)
