As with every previous version of Acrobat, this one includes the special half-as-fast enhancement.
Now you can do all the work in twice the time!
They must really work hard to make each version slower when computers keep getting so much faster. Truly a feat of engineering.
Well... It's not exactly like that.
Personally, I am getting more and more pissed at Adobe. The last Photoshop version that actually wowed me was 4.0. With every new version, the app seems heavier and more bloated...
Adobe can't really update Photoshop, Illustrator or InDesign quickly enough to make them compatible with Leopard. And I don't accept the excuse that "the codebase is too large, blah blah blah!"
Adobe can't accept that Apple will deprecate Carbon in the future. They don't seem to have any plans on using Cocoa for Photoshop or any other product.
Just take a look at Pixelmator. It offers almost everything Photoshop 3.0 offered, with some nice additions. And it's written in Cocoa by two or three guys, IIRC.
Apple should get more serious and get these Pixelmator guys working for them. With Apple's team, they could make a Photoshop killer with it, easily.
Apple already sort of killed Premiere with Final Cut. I am not sure about Lightroom vs. Aperture...
I don't mean Apple is the only company that can deliver good software, but I trust them more than Adobe.
