Why I'm not buying an 800? I can't afford one! Everything else is somewhat less relevant.

I disagree with most of your points on principle and how I use the device. That said, 6) is extremely valid and I've heard nothing comforting about it. The devices are both ARM architecture --- the switch to armel was supposed to enhance compatibility with future devices supporting v6/vfp, as far as I understood it.

Developers of open source software develop for the systems they own...I really hope this won't become an issue.
