This is my first thread/post! I am finally making the switch from an old Windows 15.6" laptop to a brand new Mac! But I'm unsure of which Notebook I want :/ I don't currently have a monitor, besides my 42 inch full HD Plasma TV that sits on my desk. I'm a university student studying management and so the computer is only for personal use not work intensive means, e.g. itunes, web browsing, word documents, youtube etc. (No photo or video editing of any kind) So my question is as follows: is the MacBook Air 11" usable *AS A MAIN AND ONLY COMPUTER* without a monitor? OR: Is a 42 inch Plasma screen practical for use as a monitor/13 inch MacBook Air more favorable. I have tried using a 10.1" netbook and found it a little cramped (then again the trackpad was abysmal and the keyboard wasn't full size, plus the air has an inch and a half larger screen). I apologize in advance, I know there are similar posts but I couldn't find any with the exact same factors.
