Obviously if I were surfing I'd not want airport off but I'm often where I
don't have access anyway so why have it on?

What's wrong with the batteries is that they are *smaller* than the ti
batteries either to save weight or to save a bit of space. Note: I bought
this machine with my eyes wide open - had longer battery life been more
important to me I'd have bought the 12 inch. 80% of my usage is between 3
job locations and home so I'm mostly on electrics.
