For work? Just as a home computer? What is it going to be used for.
If you want a home computer, I really suggest you go with Windows considering how you can get a PC of the same quality for MUCH cheaper. (Not to mention the fact that you can't really upgrade the hardware on Macs.)
However, my brother who's a fan of Macs once told me doing so can lower the lifespan of your Mac. He has a tendency to ramble but to summarize it it's because Mac operating systems are made to work best with specific set-ups, which is why they have such a long lifespan when compared to PCs even when ignoring that there are more viruses around for PC than Mac.
However with Steam being released for Mac and more and more Steam titles being released for Mac, if video games are one of the main reasons you use a computer than Macs are suddenly looking more and more attractive.
Oh, also, here's a list of games currently available for Mac on Steam.
At the least, get an Asus gaming laptop. In fact, I just bought one the other day for $800 and the specs on it are amazing. 4 GB RAM, an i5 intel processor rated at 2.27 GHz, an NVIDIA GeForce GTS 360M graphics card, and a little under a 500 gb hard drive. Holy damn is this a beautiful laptop. (Not to mention it has a great keyboard on it.)
But yeah, if you want gaming, I suggest you get a PC.
(Also, the whole "Mac's don't get viruses" is simply because of how few people use Macs. My thoughts on it are, if you're dumb enough to get your pc infected with viruses, you shouldn't even own a pc. Oh, and, even though Valve just recently released their source games for Mac, doesn't mean they run all too well on Mac. In fact, I've heard a SHITTON of complaints from TF2 players that play on Mac.)
Also, if you do go with a windows gaming laptop, ask any of your "techy" friends to help you shop around for them. Give them a price range and they can usually come up with the best laptop for your needs rather quickly.
(Also, don't go with Alienware. They have great hardware in their machines, yes, but I've heard so many horror stories involving the lack of sufficient cooling in them thus causing them to melt, and then Alienware simply refuses to acknowledge this and pretty much shits on the unfortunate people who have this happen.)
You can browse forums on a PC just as easily as a Mac.
Mac's are nothing more than overpriced, harder to modify PC's.
If your IQ is under 100, get a Mac, if you're not retarded, buy a PC.
(I mean, really, all the "super cool editing software" is just as available to those who use Windows computers. I find it funny how people think they're being non-conformists and individualistic by buying Macs, when really, they're just buying harder to customize, inferior machines at a higher price than they really should.)
Woah woah woah pal, are you knew to computers or something? Macs don't handle gaming too well. I mean, they will play some games, but most games are designed to work on Windows.
What I suggest is actually building your own PC. It isn't nearly as hard as it sounds (I built one with minimal guidance and no knowledge of computer hardware), and it'll save you a ton if you know where to buy parts.
EDIT: I also want one due to the fact im tired of linux and windows i wonna give mac a try.
Mac OS X is a piece of ****. True story: I once used it. I decided to update (official software update from Apple). It kernel panicked in the middle of the update. Every time it booted up from then on, it got a kernel panic on boot. It never started up again.
I am never touching that **** again.
If you really want an inferior OS, by the way, you can install it on a PC. It'll take a little bit of work, but it'll most likely function properly. That is, as properly as Mac OS X can possibly function.
