Waiting on the MBA revision. I am now using my iPhone 3G S as a replacement in the mean time. I am highly surprised by both how much time not having laptops freed-up for me to do something else, as well as how apt the iPhone has been at "replacing" them. Not enough for creating content of any type (= work) but good enough to stay on top of things; which is probably good enough. So now, I have a trip in the coming month. I will need to do some work while being on the road. I don't mind waiting until the last minute before I get another laptop, probably a MBA. Hopefully, the MBA will be revised by then (want 4GB RAM) but it looks unlikely. Another thought was to get a cheap netbook to get by for that trip and actually wait for the MBA revision as needed (Jan?). What would you guys do?
