Hi all! I'm a computer enthusiast, but I might have overstepped my bounds now. I bought a 17" MBP back in march 11', to replace my old faithful 13" MB and windows desktop. Today, needs for portability have returned, and a new 13" MBA is on its way. As you might think, the MBA can't fully (but almost) replace my current setup (17" MBP). I don't like the idea of just having the MBA. MBA+iMac seems like the way to go. But I simply don't know if it would be beneficial to sell my MBP and purchase an iMac. After checking finn (pretty much Norway's version of ebay/cragislist), I've learned that I'll get about 75-85% of the initial costs back if I sell my MBP. That means, that if I want to swap it for a decent iMac, I must pay for it with my MBP and a noticeable amount of money. Also, I have a 24" Samsung Monitor hooked up to my mac. The 17" I currently own is a powerful machine that satisfies all my demands, except for being a little to heavy for school every day. Would you pay extra to turn it into an iMac? Do you have any other solutions? The only constant in my setup is a 13" MBA with the i5 cpu and 256GB of storage. All inputs will be much appreciated.
