If you want to waste your life with drivers and resolving obscure compatability issues then fine.
But be realistic, you're not really saving anything and you'll never put together a hardware package that's as well built as a Mac for the same money. Apple spend a lot of time and many, many $$$ designing their hardware, and I'm not just talking about looks !
If you have to buy a PC, buy an HP branded unit.... HP hardware engineering is the nearest equivalent to a Mac.
If i find that a mac is worth it ill definitely get one. Im not against mac. then again if im seriously limited by compatibility issues theres no use spending that much money on one when my PC's working just fine. I hear pcs are more of a pain in the proverbial but I need to be sure a Mac can cater for my needs. So many people buy a Mac, then install Windows in parallel. If OSX was so 'awesome' why cant it cater for everything? Im just curious.
