ARGH!!! The voices! The voices!!!
LOL!
I'm having the exact same debate as the OP. For various reasons, I have to buy a new laptop for myself. I've had a work laptop (PC) for years, but that's going away. I am SO tempted by the 13" MacBook Pro. It seems like it would do everything I need: word processing, basic photo manipulation, music/iTunes, surfing pr0n ... er, the web.

That's really all I do with it (not a gamer, for instance.) But, I want something that will be simple, low maintenance, hassle-free and keep me going for 4-5 years. I have several friends who made the switch from PC to Mac and all of them say I will love it. And, I have to admit I am rather enamored of the new MacBook Pro and it's fancy schmancy touch pad that recognizes gestures. The only downside I can see so far is that my Sony e-reader doesn't support Mac OS, but I know there's an open source program (that I already use for another function) that will convert. Likewise the Blackberry that may be in my future.
On the other hand, there's this great Dell Studio XPS that is has basically all the same features (including the backlit keyboard) that I can get for about 75% of the price of the MacBook Pro (less if I were to buy the commercial version at BestBuy, but then I'd be stuck with Geek Squad support, which I've heard horror stories about.) I know it has heat sink issues and have read you have to update the Bios and do some junkware scrubbing right away to get the most out of it. While that doesn't seem like that big a deal, the idea of having to do maintenance on the thing as soon as I pull it out of the box, and prospect of worrying about viruses and malware (more than on the Mac) for the rest of its life has me a bit uneasy. But, the price differential is hard to ignore.
I've found myself literally changing my mind by the hour the past couple of days. If I don't make a decision soon and stick with it, I'm afraid my husband is going to strangle me in my sleep.
From what I've read in this thread, it sounds to me like the MacBook would be the way to go in terms of relatively hassle-free home computing, for my needs.
If any of you experts have any advice, I would be forever in your debt.
