wouldn't it be better, instead of using another XScale processor, to wait for intel making the first reliable steppings of their planned x86 PDA processors?
That would allow to run a much larger variety of software, beginning with simpler systems like MS-DOS, over Windows 95 and XP, up to "normal" Linux distributions.
We'd not be tied to special software versions, compilig of the apps especially for the PDA etc., but just use the stuff we can buy or download as binaries.
It was posted here some time ago I think, but for those who don't remember:
(Also search google for "intel sells xscale")
Personally, I have used the HP 200LX (x86-based palmtop developed in 1993 with 186 8MHz CPU and 640kB RAM, running DOS) for about 8 years, before I switched to the Zaurus in 2005.
The Zaurus is great in terms of screen, speed, touchscreen, Multimedia etc.
But the 200LX was far superior when it comes to usability of thousands of available software programs, downloadable for free from the Internet.
With the zaurus, I could never reach the level of productivity I reached with the HP in even a shorter time than I have the Zaurus now. And that's only due to missing software.
I can not even say the Zaurus is more flexible due to the Linux system.
DOS is also VERY flexible when it comes to configuration and batch programming, if you only know some hidden tricks.
If I hadn't migrated all my PIM stuff etc. to the Zaurus already, I'd seriously consider to switch back to the HP.
Would waiting for a PDA-x86 processor be an option for this project?
