Keep in mind.. Its a beta. As such, there are problems.
The biggest one, apparently it makes you redownload some games. Nobody knows why, but its all over the Steam forum. Happened to me, so now i get to redownload MW2 on my $h!ttastic internet
Yea it made me redownload Company of Heroes.
Fix in case anyone else has this prob:mine isn't working quite right. the large game icons don't display and i can't browse the steam store or community page/friends list. it just sits there then gives a "testshell-error:"
