One thing you might not have considered is that many laptops no longer have a separate key for the applications (the thing sighted people think of as the right click menu).  Some have a key combination with the fn key and right control key to do the same thing.  Most laptop keyboards are awkward for anyone with other than small hands, and key separation ranges from okay to horrible.  I really suggest buying locally if at all possible, a laptop that may be fine for one person might annoy someone else.  If you can get by without portability, get a desktop, then you can plug in a real keyboard and good speakers more easily.
