I was mainly curious as to how you survived with a 13" TV all day and thought maybe it's because you are sitting right at it all day. Although that still seems awfully small for anything other than occasional viewing. It seems like I'd be missing a lot of the movie on a 13"... but that may just be me.
I wouldn't see any issues using the 17" LCD and at least you get a little more screen for you and your gf to share.
