I am a proud iMac user, but starting to crave some level of portability around my house. I love having a gorgeous 27" LED IPS display when I feel like being in my home office, but there are times I wish I could just have my Mac on the couch as well. I tried the iPad, but having a true 3rd device to pull up a website was a little bit overkill so I sold it, but now I miss the portability option. The iPhone's screen is just too small for anything meaningful. Unfortunately, there is a very high cost in going the TBD+MB route. Should I bite the bullet and do it for the portability or just get the iPad again for bigger-screen around the house Apple entertainment?
