Hi guys, I'm writing to make a good decision for my large secreen needs. I've a top upgraded 13" MacBook Air 1.7Ghz, 8GB ram and 512SSD. I like my MBA. I use it for surfing the Net, blogging and some office document. I don't use Photoshop and other programs, either. Now I'm in between buying a Thunderbolt Display next to my MBA or buying an iMac. Which one do you advise me to buy according to my needs? Thanks in advance for your responses.
