Hello, guys. I'm currently waiting on my MBP 15.4", 2,4 GHz, 7200 RPM to arrive. Basically my idea was that it would replace my desktop computer completely (a 1.5 year old PC): I would connect it to my DELL 24", external keyboard / mouse when I'm using it at home, and when I needed a computer someplace else, I'd, of course, have that option as well. I'd probably buy an external hard drive (500 GB or more) for storage as the hard drive on the mbp isn't that big. I'll use the mbp for some gaming, photoshop and organizing photographs with iPhoto for the most part. The question wether win xp and windows based games will run well on mbp (with boot camp) is pretty much: yes it will run just as well as on any PC with simular hardware specs, right? I kinda stopped worrying about this cause this is the answer I see most people give regarding this. What I'd like to know is how well does MBP function as a desktop computer. By that I mean having it turned on for many hours per day, power cable plugged in etc. I know the MBP runs WoW well (i've seen some vids), but would it run WoW well for say 5-6 hours (I don't play WoW, just an example)? I mean, is this computer designed and capable of staying on for many hours/day or will such use somehow affect certain hw components eventually . I never owned a laptop computer so I don't really know the answer to this one. I know it's a weird question, and I hope you can understand what I mean.
