I'm playing with my 9600 this evening. On the upside, using Photoshop 6 to change the screenshot file formats for posting here is lighting fast. I think PS6 is one of the few programs that can actually use both processors in this computer(they are not even seen in OS X).
On the downside, the new forum software is still abysmally slow on this computer. Back in the days of vBulletin, I could pretty comfortably browse this(and most other sites) in desktop mode even on a 604-based computer in Classilla. Xenforo will work okay with TFF on most G4s and even faster G3s, but Classilla seems to only really be happy in Xenforo on a fast OS 9 system like a 1.25ghz MDD.
The page renderings are also really weird.
