I'd like a little notebook like this new Macbook Air, it would fits my needs for a thin portable client to replace my actual macbook (I ssh a lot to remote workstation when I need horsepower, coding and so on). Still something puzzles me: * No Ethernet. I really can't trust Airport, i have a 13" Macbook and sometimes Airport fails hard (without mentioning the speed transfer). * No upgradable. I understand the design choices behind this nice netbook (or whatever), but what if the ssd breaks? Or the ram? I'd need to buy a new one. Maybe my needs would be better fitted by a standard netbook. The truth I am ashamed to confess is that I am too confortable with OSX.
