It’s bizarre to see Techmeme headlined by a post on the new MacBook Air that is wrong about everything, but at the same time fails to mention the one problem that actually does make the Air a non-starter for any serious user - the lack of a user-replaceable battery. I’m on battery 3 for my MBP, and routinely need 2 to make it through a powerless session. To my mind, it’s a stunningly poor design decision.
