Laptops are nice. I own two. I bought the one I'm typing on off e-bay for $200. It's a damn good machine, with the best sound I've every hear on a portable device (a helluva lot better than tose $160 iPod speaker docks you can buy. Uggg.. those sound like this by comparison. Also, this laptop doubles as a cdplayer (no, no MP3, only audio CD) when it's off... it's pattery last about 10 hours in cdplayer mode, about 3 1/2 in regular use mode. All in all, a steal. (1ghz, btw)
So, here's my take. in three years, you'll wish you had that 360. Unless you have a need for a laptop, don't bother. Reason? You can save up some $$, and get a cheap one off e-bay. (I recomend Compaq 1800T's... they're the same one I've got. Heck they're decent enough to play CS and only lag some.)
C'mon.... an Xbox360 is the thing people are drooling over right now. Atleast keep your braggin rights for another few months.
Oh, as a note, if you're looking for a portable device that's not as expensive as a laptop, try this:
