Hi all With WWDC around the corner and the probable upgrades, I'm thinking about buying an iMac. I also have a 15" pre-unibody Macbook Pro, about 4,5 years old (actually 3 because of the 8600m gt issue). I can spare the money for a new iMac or a new MBP, but as I'm still a student, not both. So if I buy the iMac and my MBP (which I do need for school, music...) breaks down shortly after that, I would be in trouble. So I'm looking for the lifespan of your MBP's. So I can get an average of what these boys can do. Of course it's different for everyone because not everyone uses them as much as the other, but still it would give me an image. I've enabled the multiple answers as some of you probably had more than one. Edit: keep in mind that with lifespan I mean till it breaks down. Was a bit unclear, sorry. Thanks!
