I'm coming to you live from my MacBook Pro I bought in April 2007. I got it because I needed a portable -- a craptastic Dell wasn't working, dude. It's been great, but for the past year it has had what I figured were video adapter issues. It locked up from time to time and started taking longer to boot. I let the Genius Bar examine it about a week ago after making every fix I could (new hard disk, clean install of Snow Leopard, new battery -- old one was going bad anyway). Bad video adapter WAS the issue. Today, it started going into an endless reboot at times. So, it's time. I don't really need the portability as much anymore thanks to my iPhone and a potential iPad in the future, but I sure as hell love taking my software to work when ours craps out. But we're getting a huge equipment upgrade soon, so that won't even be as much of an issue. But it's hard to let go of my main computer being portable. I was REALLY impressed with the 13" MacBook Air after using it in a store because it is SO FAST. But I don't even know if I could jam just the essentials on an internal 128GB disk. I almost filled up a 320GB hard disk and just upgraded to 500GB (ouch). I can fix that by moving music, photos and the videos I haven't moved to an external to that drive, but then what's the point of a portable? So my head is telling me to go with an iMac. My dad got one not too long ago, and they're quite awesome. I'm on a 2.26 Ghz machine and his is 3.06 Ghz. I like to use HandBrake for some of my movies, and that's obviously awesome. I'm also using iMovie more to make videos, and that also loves it some horsepower. I can get way more bang for my buck on an iMac plus easily get enough storage. So if anybody has advice, I'd love it. I'm reading up at the buyers guide and also debating a refurb, although I really want to buy through Best Buy instead of getting ANOTHER credit card because of financing.
