Email and skype, ok that is pretty simple. Along with being fast. So I recommend pretty much any computer you can buy at your local store, just make sure the computer has 4-6 gigs of ram. Other than that, the store wont sell anything with parts that are on the low end for that type of work. I still would like to know what your disability is like just in case I need to refer you to something else. Also, you can just post what computer you are thinking about getting and I can tell you if it would be good or not.
