On this one.  First Linux + jffs (jiffy file system used on 770/n800) is a lot 
less likely to be corrupted as a whole than windwos.    Normally this means 
that the GUI is locked up rather than the system itself.  On my 770 (and my 
laptop too sometimes) if I have an app that locks the GUI, then, SSH to the 

SSH into the system, from another box, then either kill the offending app or 
if what to kill isn't obvious, just do 'shutdown -r now' (without the quotes) 
or 'reboot'  and the box will shut itself down cleanly, and restart.  A lot 
of the differences in how the OS's react to a hard shutdown center around how 
they view/use a file.  Windows always writes back any file it opens.  Even if 
it opens it only to read.   Linux on the other hand writes back a file only 
if it changes and permissions allow writes.  This helps prevent a lot of file 
corruption and fragmentation IMHO.  (Yes I know this is an overly simplified 
explanation but I don't want to either bore or exceed my own ignorance
