Newly converted mac guy here. Had a cheap, plasticy gateway before and it literally started falling apart after 2 years (not to mention I was getting really tired of vista). So I bought the 13" 2.53 macbook pro and I love it. But I find myself babying it to death. As with any new (ridiculously expensive) toy, I'd say it's typical for the first few weeks, but from what I understand the unibody construction makes this thing pretty tough. Not that I should start using it to prop up table legs or anything, but I mean, it is pretty durable right? A few other quick questions I had in mind being new to macs and whatnot: -any problem with using it on my lap or should i use it on a flat hard surface? -I have it in my had that when the fans kick in (like while burning DVD, etc), its exerting itself too much. Tell me to stop being so paranoid. -lastly, does hard drive space effect performance? for example, i have about 180 gigs left from 250. Does it get worse when you reach "x" number of gigs? -and lastly lastly, thanks for your patience, and yes I'm an imbecile.
