I'm using an iPad Air and really enjoy it, but I'm often limited by what it can do and would like a "full computer" to use on the couch. I already have a dedicated gaming computer, so this laptop would only be used on the couch and possibly outside on the front porch or on the table in our patio. It will never be used for serious work but just to surf the web, play some light indie games that work on the couch (with a trackpad), etc. The 13" has a much better screen but it seems so big and bulky compared to the 11", but the 11" is a bit tiny when placed on a lap and viewed "far away". Any opinions?
