So I recently purchased one of the new aluminum unibody Macbooks, absolutely love it, it's a beautiful piece of machinery. I've been considering one of the 24 inch desktop iMacs, for more graphic editing work and gaming (I have a Macbook, not a Macbook Pro). The Macbook has been... sufficient for my purposes, but I don't doubt that the iMac would be an improvement for when I am home. The screen real estate alone would be amazing. I'm wondering if anyone here has used both, and can advise me as to the wisdom of such a purchase. Is the improvement in performance that notable, or is it more minute and I'd be just as well off getting the Apple 24 inch display to tether my Macbook to. Is it really worth the cost, I'd be getting it in addition to the macbook, rather than replacing it, as I'd still like to keep the portability of my macbook available. (It's possible at someday I'd replace it with a MBA if they ever become cheaper with SSD, as I mainly want the laptop for portability, not performance). Any advice one way or the other would be great. I am sure I'd enjoy it greatly if I got it, like I have every Mac, but am wondering if the upgrade in performance would be noticeable enough to warrant it or not.
