Hi, I recently bought the MacBook Air 11 inch i5 with 4GB of Ram and 128GB SSD. Now, I'm thinking about making a better desktop setup. I am a normal computer user; web surfer, email, iTunes, Netflix. My question is: should I spring out and get the Thunderbolt Display, or buy a base iMac 21.5 inch based on my needs? Is the Thunderbolt Display worth the money, as in in the performance worth the cost? My predicament is that I could get a full computer for just 150 dollars more or so. Any insight would be greatly appreciated!
