Finally bit the bullet...

and slapped down $200 at Crucial for a long needed 1 Gig DIMM for my 12" Powerbook G4. Wish I'd done it sooner. Noticable performance increase even on stuff that shouldn't (typing within terminal or right now!) and Netbeans is actually usable.

Oh, also saw the 13" MacBooks at the Apple Store in Clarendon, VA. Ambivalent about the 80s retro "chicklet" keyboard, but the feel was better than the old 12" iBooks. Something about the screen aspect ratio was "off" though.
