Found at a flea-market - WOW I paid over $400.00 for each of my C3100 and C3200. Consider yourself lucky.
Keep it!! The Zaurus line is still one of the more advanced mini computers that you can find, especially at flea-market prices.
I cannot answer all your questions, as I only installed pdaxrom for just a few minutes (to upgrade to pdaxii13, when it was first made available).
I tried the spitz pdaxii13 setup on my C3200 and found it too slow for my taste at that time. (I just came from Cacko)
Then I started over and just installed pdaxii13 Akita to NAND. This has a lot fewer applications and general stuff than the spitz version has.
It also seemed to have a faster response time.
While on the subject of speed and pdaxii13, Meanie (the author of pdaxii13) suggests to disable schim in pdaxii13config if you dont need to use it.
Schim is loaded at default and slows pdaxii13 down quite a bit (my personal opinion)
Now, with pdaxii13 Akita installed to NAND only, I later installed "Heavy" applications, such as Firefox, Abiword, etc. to my hard drive.
Set up this way, pdaxii13 has a "comfortable" response/speed for most small tasks.
Opening and using major heavy apps are always going to be slow compared to smaller "simple" apps.
I have another Zaurus, C3100, and It has always ran Cacko.
I recently found a thread in the Angstrom & OpenZaurus forum about HowTo dualboot Cacko & Angstrom.
https://www.oesf.org/forum/index.php?showtopic=26351The actual page with fairly easy instructions to dualboot Cacko & Angstrom with kexec is here:
http://www.linuxtogo.org/gowiki/AngstromAndCackoThe below is just my opinion, as I only have had Angstrom installed for 5 days now.
I find Angstrom a lot more difficult than Cacko or pdaxii13, because a lot of basic stuff doesn't seem to work right away, such as USB host/client stuff.
And in Angstrom, to get stuff working, you need to use a lot of console commands, and do a lot of research to find solutions.
I have probs with console commands because I always have to look them up because I forget them if I don't use them regularly.
On my optimistic side, I find Angstrom to be pretty cool, as it is now using 2.6.24 kernel and is being currently updated/developed.
I haven't tried Debian yet. It seems complicated to get installed and setup.
