Hm.
Well, things are getting really complicated. I think I left out a really important point that
txnoob seems to have pointed out:
...The issue with this statement is, besides going the "Hackintosh" route, you cannot get the Mac OS any other way. Not only that, a lot of the apps for casual users are so well integrated and much easier to use and cost much less than PC alternatives. iLife and iWork as examples. There's nothing as easy to use as iWeb, iMovie, or iDVD for the PC. I would argue that iWork is not an adequate replacement for MS Office Suite, but it's also Half the cost or more. The operating system is the prime jewel on the Mac platform. So to me what you really need to decide is do you want a change to a new way of computing, or do you want a faster computer on the same platform. You can have a computer 3 times as fast as a Mac spec wise, and still be stuck with Windows. From what I understand, the OP is fine with his current windows machine, and more that he wants to try something new.
It really
is true, and what I really want is to experience the Mac platform. My problem is that I have a computer that works fine, so there's no real driving force behind spending $600 on
another computer.
You guys have been really nice in pointing out the advantages of maxing out the RAM, or just bumping it up, because 5 years down the line, newer programs
will demand more memory. Unless of course, Apple comes out with the
newer Mac Mini, and I'll be posting here again, asking you if I should buy
that then.

Don't worry
Also, the problem with the old Mini is that it does not feature the GeForce 9400M. Without it, it'll be impossible to run the games I can already play (albeit with a mediocre framerate).
I think the only profitable decision would be either to wait and buy a mac mini refurb as
flopticalcube mentions:
If you don't NEED to upgrade you should probably wait. In six months or so they should start appearing on the refurb site for up to $100 off and you may be able to snag one with Snow Leopard by then.
Or to buy one now, but somehow put my current computer to good use. (I don't think selling it would get a lot of munnies)
Aye, confused again.
Thank you once again for helping me out

My experience on MacRumors has been surreal
