i work at the office on an new imac 24' and manage to travel with my iphone as long as it is a short trip of 1-2 days, however when i travel for more time then i miss having a laptop, as i need to start answering longer emails, browse for longer time on the web, occasionally write letters etc. which is not always practical with the iphone. i was thinking of getting the new macbook air as a second computer to travel with. however the emergence of the netbooks at a price of 500 usd vs a macbook air at 2000 usd makes me wonder what the more sensible choice would be. what do you recommend? thanks. ms.
