I think different people have different use cases. Not everyone is tied to legacy apps. I’m sure a lot of MacBook Airs are just used for web and email. Look at the Macbook, it’s trade-offs are for people that want long battery life and probably do a lot of typing. Think journalists on the road, on long flights. I’m sure that market would jump at longer battery life for majority of apps. As for not being able to install Windows, I’m sure you could if the x86 front end was in silicon (again, think Transmetta), but it is probably not for that target market anyway. As for Apple supporting two systems, I don’t see the problem. They did it for the 68k to PPC and PPC to x86 transition, and when you own the entire stack, including system language and build chain, it probably isn’t as big a deal as cross platform with different APIs and paradigms.
