I just bought a 27" iMac with the QC i7. I'm excited, to say the least -- my last laptop was destroyed because I mishandled it. That was my initial reason for deciding to buy a desktop, actually -- I decided that I needed a computer that sits on a desk rather than one that I can throw around, at least as my primary machine. I do web development and graphic design, so the large screen coupled with the quad-core chip made the iMac seemingly make sense. I'm having second thoughts, however. I do think I need the portability -- in very limited circumstances, I need a computer. I used to do some work on-site, and while I could get away with not doing so, I at least want that option. Moreover, I will be returning to school eventually and I would like a laptop to bring around campus. The thing that intrigued me still about buying an iMac is that I could probably get away with a laptop like a 13" MBP or MBA for my portable needs (web development, internet surfing, light Photoshop). My prior workhorse was a 15" MBP and that was uncomfortable to carry around (I'm small and lanky -- I don't do well with significant weight -- but I enjoyed having a portable powerhouse). Does anyone own both? If so, would you recommend such a solution?
