MacBook makes sense. First you have the iMac, which is the "home PC" for "myself" ("I"), and then (in the future) I predict they'll re-release the PowerMac as just "Mac." "The All New Mac." And so "Mac Book" makes sense, because it ties in the name "Mac" with the previously recognizable name "PowerBook." As for the "Pro" part, they'll no doubt soon release a MacBook (Non-Pro) for students and average users.
Boot Camp is a pretty clever name. As for the "actively lock out", I agree with >>10. Why should Apple have to pay the price for another companies fondness for old-as-hell technology? Linux can use EFI. Solaris can use EFI. The BSD's can use EFI. Why can't Windows? Microsoft deserves their ridicule.
