I use Edgy @ home too (I started with Hoary). I moved to Ubuntu after using Gentoo for 2 years. I learned a lot with Gentoo, but mostly spent time fixing things after doing upgrades. Ubuntu, just works out of the box, so i spend less time tweaking. Using Beryl & Aiglx, very stable so far.
Same issue with the multiple boxes on pdaXrom, not sure about Angstrom GPE, I haven't connected reciently, I too use flash card reader or scp via wifi
Cheers,
