They should wait a week and buy the iPad 3.
I wouldn't think most pilot would be needing the boosted processing power or be doing or playing HD games and watching HD movies etc etc or doing any sort of extensive editing on those devices so why spend more than they need? And I'm sure for the general consumers there will be a hell of a lot of use for power processing because we are spoiled for them. I can't wait to get the iPhone 4S myself, a huge upgrade from my "ancient" 3gs. Don't get me wrong, i've been able to use a lot of features and apps for everyday productivity with the 3GS. Just that I'll be able to do a lot more and faster with the device.
It all depends on what is most beneficial to the cost of use of any devices. If the full potential of a device is barely reached, might as well use the one that is potentially matched to that of the end users.
