Yes I can read! But apparently you have issues comprehending what you read.
What has "he already got"? He said he has an iMac and wants something portable. Just for your info there are portables that have more to it than the 11" Air. He was asking if the 11" Air would be good enough. I gave him my opinion based upon my experience. Nothing more, nothing less.
Not to mention he asked about the 15". Which is what I suggested he do. So yes I can read. You might want to try it sometime yourself.
If the 11" Air works for you, then good for you! It doesn't work for me.
