I just got a MacBook two months ago (as my desktop PC has too many things wrong with it to count), and I absolutely love it. I don't know much about computers either, but Apple has some service where they will transfer all your documents and such from your old computer onto your Mac. It didn't take me that long to get used to the Mac format, and I now find myself trying to use Mac keyboard shortcuts on my worthless PC, which is still miraculously running.
I think there's another topic in this forum about Macs vs. PCs, which I can't find right now, but it really comes down to personal preference.
