>Might not be that bad, but what window manager supports that with quick (tiling) keyboard shortcuts? Resizing windows "free-hand" is lame.
Maybe this was a rhetorical question, but this is exactly where tiling window managers excel. I have been using wmii for a year or so now, and it's amazing how much screen space I have, and how useful it is.
(Of course, this is not a mainstream suggestion, since ordinary people would probably not appreciate learning to move their windows with Win+[vi keys]...)
