1005HAB has a 3 cell battery (the one that i got), and i think it lasts about 3-4 hours with a normal version of xubuntu.
iv been really happy with the wireless speed (haven't had any other netbooks, so i don't really have anything to compare it to). i have experimented with google wave, and it actually had a really good response time.
the kernels of most distros don't come with the required internet drivers yet (i think the next ubuntu will come with them), but its pretty easy to install it: http://ubuntuforums.org/showthread.p...&highlight=Eee
the front mic doesn't appear to be working atm (towards the bottom http://crunchbanglinux.org/forums/to...-users-wanted/
also, i find it to start up the normal xubuntu install suspiciously quickly. it may be my imagination, but i think its beating my 3.16 dual-core desktop (running mint) :-D.
