Decent and generally fair review. I don't think the wireless capabilities , fixed RAM amount or non-user replaceable battery should be cast in a negative light. I understand where you're coming from, but these are stated up front. If you want to replace your own battery, or you want to have 4GB of RAM in your machine, the Air isn't right for you, simple as that.
I agree that out of the box the Air's multitouch is pretty useless, however, you should check out
MultiClutch if you haven't already. It's a wonderful extension of multitouch to all Cocoa apps. If nothing else, it shows what multitouch will be able to do once more third party developers begin to integrate its uses. This will hopefully be aided by the introduction of multitouch into the MBP, widening the base of machines that are multitouch capable.
Definitely second the need for Apple to hastily bring movie rentals to Canada! I can't imagine why any Canadian would buy an Apple TV with the knowledge that it's most powerful feature isn't available to us.... at least for now.
