23"
I arrived home this afternoon and found that my new 23" monitor had arrived. This thing is fricken' awesome! It's so crisp, clear and BIG!! The only bad part is that I thought it supported Windows out-of-the-box - by having a VGA port. No such luck. It looks like I'll have to buy a DVI male to VGA male adapter - or possible new DVI video cards. New video cards would suck since I'd have to buy 3 for my two Linux boxes (Fedora and Suse) and one for my Windows box.
Regardless, it plugs right into my PowerBook and works great with it.
