I bought the cheap "peasant edition" 11inch MBA yesterday. It is amazing! Obviously I don't keep much on it, all my files are on my iMac server at the moment, but even considering that the air simply flies along. it is remarkably quick. For a relatively inexpensive mac to just use for browsing, writing, etc the cheap air is an amazing machine. In fact I am in the process of making a pocket in my coat in which the MBA will fit, it is so small. One thing would make it perfect and i am amazed apple haven't done it yet, it needs a SIM card slot in the back so i can use unlimited free 3G internet, like 3 offer for 15 quid a month,with it. if an iPad has a sim slot why dies a mac not?
