Running Xist-20050131 same emac as previously, no issues,
Running it on a older 466 g4 256mb 10.3.7 runs perfectly fine.
front app: 17% - 19%
hidden: 3-5%, heh, suspiciously low, but the terminal command TOP says about the same.
I should mention that it only skipped once even though I used safari, activity monitor, quicksilver and iTerm. And the time it skipped safari was loading a page with tons of flash crap ads
Looks... different, but well I should rather STFU about the looks, I can't stand the brushed metal look

Only thing i found strange was that the 'very cool' icon didn't show up on my eMac, but fine on a old g4 running exact same system
thanks for the update (using it every day
