Hi Wightout,
For the most part you'll find that a Mac of roughly similar performance to a given PC config. will be significantly more expensive. That said, Macs have design features (stylistic, for example) that appeal to a segment of users. The Mac OS and included software are often said to be more "user friendly" than Windows (any flavor) or Linux. It goes without saying that those considerations are highly personal, and the best course of action is to choose the platform which best fits your needs and budget.
With Macs your choices are quite constrained--Apple is the only supplier. PCs come from lots of sources, Dell being the largest. Much more software is available for Windows, but pretty much anything can be done on Macs with careful software selection. Exceptions are with some kinds of very specialized stuff, but you sound like a user with modest needs. If you don't have lots of experience, the Windows world can be intimidating just because of the range of choices available. There is such a thing as "too much of a good thing". One advantage often cited for Mac OSX is the apparent lack of viruses/trojans/spyware that can make living with Windows exciting. For nontechnical/enthusiast types that advantage is definitely worth careful consideration. In the Windows world, XPSP2 has made things much better, but you still want good anti-virus and anti-spyware software running and always updated.
Really, the best thing would be for you to be able to muck around a bit with both platforms to get a feel for what you like best. You can find PCs everywhere, but Macs can be a bit tougher. Check for an Apple Store near you, or possibly a CompUSA. Apple has tried to place experienced Apple staff in at least some of the CompUSA stores--they would be best able to answer questions and demonstrate the hardware and OS. The regular CompUSA staff would be of little use whatsoever.
