The speed. The 64Bit version in particular is a big jump.
The Fluid Canvas Rotation.
The Content Aware Scaling.
Hate:
The Adjustments Panel. Photoshop for Dummies.
The pretty zooming and 'flick' panning. looks trick. makes you feel nauseous. Can be disabled thankfully.
Adobe's lame and constant excuses why they aren't producing 64bit versions for Mac even though the bulk of their (legitimate) user base uses that platform. come on guys - no one bought that excuse for CS3 - its even less credible this time around.
ya i got this the day it was out for both mac and pc.. love it... started acting up with illustrator registration but there was a tiny fix for it... its nice but for some reason i still like cs3
It seams that most of the really annoying stuff they have added or changed can be disabled or ignored which kind of begs the question why they were added in the first place. From early impressions I would say that Adobe should have rewarded their customers by making this a free upgrade like a CS3.5 for instance rather than launching it as a swift new version. CS3 was only just at the point of being stable as it was so for the sake of the few new useful features it really seems like they are just ringing the punters wallets through the mangle to get every last drop of cash out of them.
Is there any possibility that CS3 was driven out the door entirely by Apple's Intel switch? Perhaps if that had not happened CS4 would've been CS3. I know there was push by users for intel compatibility because CS2 was pretty slow under emulation.
neither CS3 or CS4 have been optimised for Mac OSX yet - Adobe say that Apple didnt release the 64 bit OSX source code to them in time which is total bull as its been available to developers for almost 8 years now.
