the times i've connected wireless, the speed is dreadful.
using speednet,
it was about 0.03mbit.
on the cat5 ethernat cable, (the libraries on the computer) it was like 95mbits download, and 70mbits upload.
also some netbooks actually can't connect to the internet cause they don't support the software.. or rather the software doesn't support them.
don't get anything slower than an atom 1.6.
don't get a 64bit OS either.
and no don't download torrents.
they track every kb you use.
and yeah some websites don't work.
for instance i can't get on quakelive
