I'm going to put this out there right away, I'm not looking to buy something top-of-the-line.

Here's the deal, the only programs I'm absolutely certain that I need to run are photoshop (I'm not quite sure which version I'll get, but I'll at least have Element 4.0; I'm using 7.0 right now, but I won't be able to easily move that to another computer for, what I believe to be, obvious reasons) and other software related to the Wacom Intuos3 I'm using.

I understand that it's possible to get Microsoft Office programs on a Mac (without installing all of Windows, mind you), and I'd prefer to do that as, in my past experiences, moving documents from Macs to Windows is an absolute nightmare. If anyone knows a little bit more about this and can tell me if it's absolutely necessary or not, I'd be very grateful.

Currently, there are no plans to run games on the computer. If I decided to do that down the line, I'd probably look into dual-booting with Windows (unless anyone else has a better suggestion).

The only thing I'm unsure about is what I should have in the way of hardware. Given what I've requested in the above, I don't imagine I need anything particularly spectacular. I can run all of that stuff just fine on the three-year-old piece of junk I'm running now. I imagine, though, that in the future I'll probably want to run some different programs that might require a little more from the computer. I have no idea what to anticipate, but knowing me, I'll probably try to use something of the sort.

I can handle a computer just fine as long as I don't have to be part of all the hardware on it. That stuff baffles me.
