With more and more content being downloaded, we don't really burn CD's and DVD's anymore, it seems like the DVD drive is really becoming a one-time tool to install software. It seems odd to lug around a component that gets so little use. (yes, I am sure some people need the drive daily, but that must be the exception at this point.) I wonder if Apple will drop the drives in the next revision? More room for a bigger battery? Less weight? Thinner? If not in 2010, it'll happen sooner or later, I guess.
