I am looking to get a new 11" Air for law school come fall to replace my current MBP and I am curious if my 2010 13" MBP will be sufficient as a desktop when paired with a 27" display, keyboard, trackpad, and 1TB external HD. It has a 2.4 GHz Intel Core 2 Duo processor, 8GB 1067 MHz DDR3 ram, a 250GB HDD, an NVIDIA GeForce 320M 256MB graphics card, and its running 10.8.2. I mainly use it for paper writing, some excel spreadsheet work, email, recreational and research web surfing, music listening/downloading, and a little movie watching/gaming. To make my MBP into a desktop I would have to purchase the display, keyboard, and trackpad for around $1k. On the other hand a new/refurbished iMac runs around $1600-$1800. I like the idea of saving $600-$800 to put toward an 11" Air, but I don't want to shoot myself in the foot later on in an effort to save some money. If anyone has some advice it would be greatly appreciated.
