had it a couple months running as my primary now...
going to reflash the former primary w/ Maemo Freemantle + Power Kernel... in 3½ yrs i have used N900 as my primary it never crashed and misbehaved that much
possibly had more crashes while using the device one way or the other (phone call , browsing, copying files, doing a ls in xterminal, trying to take pictures, whatever...) then in the 3+ yrs before
1 out of 5, honourable effort but completely unusable :|
