#3: Well, you won't find many wi-fi devices that can do much more than 3 hours of active use. I get about 4 hours from my N800. My PDA gets about 20 minutes.. and the N800 can stay online for much longer. A couple of days or thereabouts. Very unusual.
#7: You're experiencing out-of-memory problems then? I'm curious about what applications you run. Myself, I haven't even enabled swap space, so I'm running with just the 128MB of RAM as VM. Never had an out-of-memory error. But I usually don't run more than 3 apps at the same time.

My wishlist for today:
a) Global panorama/landscape support.
b) Some of the applets waste way too much space. When it isn't allowed to arrange them in an overlapping pattern, then there must exist no limits to how small they can be adjusted. Some applets refuse to be reduced below a certain limit, wasting lots of space (clock applet in digital mode), others are good citizens (3party small launcher).
