Agreed, I've only had mine a few months now but have been much more impressed than I thought I'd be, both in terms of stability and functionality (especially with many of the excellent tweaks and apps from developers on this forum).

In the first week I installed everything I found even vaguely interesting (including from testing & development repos) and the device became quite buggy (which you've got to expect - that's why devs put their software there and why the repos carry severe warnings).

But having tried everything out, and decided what was really stable/useful for my needs, I reflashed with PR1.3 (including emmc) and have since been far more careful about what dev & testing apps I install. That has kept things very stable since, and I usually only reboot when I want to play around with NitDroid (while I'm keen to keep track of what Android has to offer, I find it much clunkier and less refined than Maemo, except for its nice way of handling notifications).
