Hello! So I currently have a Macbook Pro from early 2007 that's still puttering along, but I'd like an upgrade. I'm currently considering these options: Macbook Air 13" - 2.13Ghz Core II Duo, 4GB RAM, 256 GB SSD HD Macbook Pro 15" - 2Ghz i7, 4GB RAM, 500GB 5400rpm HD, Hi-Res Glossy Display, Thunderbolt IO iMac 27" - 2.7Ghz i5, 8GB RAM, 1TB HD, Thunderbolt IO Aside from the usual heavy web browsing, I also use my computer for graphic design work (Illustrator, Photoshop and InDesign), type design (FontLab Studio), and watching movies and TV. Being able to play decent games would be awesome, but not necessary. Although I absolutely love having a laptop to bring to friends houses, into bed with me, etc, something really appeals to me about having a beautiful desktop machine that I can really do work on. Since all three options will cost around the same amount ($1750), and I don't particularly travel very often (although if I had the Air, I would bring it everywhere), which would be best for my usage and lifestyle? Or, another option: Buy the iMac as my primary computer, and upgrade the battery and the RAM on my current computer (much cheaper than a new laptop) to keep it as my portable. Thanks!
