ditto on the monitor..as for ease and power, it's obviously all up to what you have in your machine..I have 8 gigs of RAM in my PC and 10k rpm hard drive plus I've over clocked it some. I simply couldn't get any faster. The keyboard is somewhat different on a Mac but not easier or harder. If you're still using OS9 then you need 2 hands, one for the mouse and one for the keyboard. There's no right clicking. I found that quite cumbersome when switching between the two. OSX has changed that to operate like a PC. I do like the way the Mac's file system works. Very efficient. Of course the biggest problem on a PC is malware and spyware that are constantly attacking it. You have to have virus protection, which eats resources. All in all, like Ron Werntz said, there's very little difference now.
PC, i like Linux too but the programs i need (namely photoshop) don't work on Linux so i never use it. I haven't used mac since high school but i remember liking it then.
I have used Macs for 15 years. I've never used anything else so the only thing I
know about PCs is what I read and hear from friends. I think the difference in PCs and
Macs has gotten much smaller in recent years. The main difference is in the OS.
Macs seem easier to use, but if you're proficient on a PC, go for it !!
I agree with Gabriel Catalin (below) about the calibrated monitor. This is very important!
I have PC at home, but have been using MAC at work for over a year. PS CS3 on MAC has a few extra options, like fading last added filter, you still can do it on PC but need a bit more time. Now I'm saving for a MAC.
I use a PC. Photoshop works pretty much the same on either, but my money buys more than twice as much PC power as Mac power. I just got a 4ghz processor, 4gb ram, 1gb vid card PC for $700. I can't find an exactly similar set-up at the Mac site, but it looks like the same power would cost at least $2000 if not more.
