a rather sad report about my 770, I apologise to all 770 developers in advance for hurting their feelings (I know how it is like when somebody complains about your software).
The web browser (Opera) continues to crash on me with random sites also sites not always make it crash, its a random thing (digg.com is a good example). I tried to reproduce it but its to random, sorry no decent bug report.
The file manager is slow as hell (with big directories) - I guess this has to do with the pre-fetching which I noticed with obexftp (accessing files on your cellphone). Also I got many very long hangs (no display update or reaction to user input) and crashes, mostly while browsing large directories. The memory usage seems to be pretty insane too.
I get around using the file manager for browsing large directories by using opera (url=file:///).
Device just rebooted/reseted while playing with WPA-PSK - I really guess it was just a coincidence. This happened while setting up WPA-PSK on my parents Linksys WRT54GS (wrt-gg). I had opera and xterm running and the connectivity-settings panel open. Suddenly the device silently reboots (no low memory waring as usual when you do nasty things with opera). No data lost! Just a normal reboot. I tried to reproduce it again - but no luck. Maybe just some problem with the wireless driver where it dead-locked itself and some kernel watchdog killed and resurrected the device (I was heavily messing with the access point settings). This never happened to me with any Linux box I wasn't messing around in the kernel.
Anyway I still totally like this thing also everybody always comes over to look at it :)
More feedback is on the way... I still need to investigate some of the things I want tell you folks.
