Need advice from Apple users

[hot_pastrami]

When it comes to x86-compatible boxes, I know exactly what I am doing. I can field strip any IBM-comaptible box in two minutes flat, and I know my way around any version of Windows expertly. I can tinker with the registry without fear, install hardware and software like it's going out of style, and get a PC running smoother than a Menthol Camel dipped in rich creamery butter.

But I know next to nothing about Apple computers. And now I'm thinking of buying one.

I'm thinking of buying one because I am trying to leave the programming racket and get into graphics design, and EVERY graphics design job listing I see requires Apple expertise. I have used Photoshop on the PC for some time, but it's just a different environment.

I want a box I can run OSX on, and which will run Photoshop and other desktop publishing apps smoothly, without choking on high-res graphics. It needs to have USB support, but I imagine most (if not all) newer Apples will. I need at least a 17" display, preferably 19" (CRT is fine, don't need flat-panel). Advice? What to buy, where to get it for a good deal? All of my PC expertise is useless in this endeavor, so I am grateful for any assistance.

Thanks.
