I would say that "just in case" isn't a good reason to spend $130 + tax(for ethernet & drive). If you find a sudden need, THEN head to the Apple store or Best Buy and get one. Or, as another poster pointed out, any old external optical drive you have lying around will work. I just keep thinking of the IBM X40 I have had for 3 years, and how I never use the Ethernet or external drive on the thing any more. I agree that it would be a pain in the neck to reinstall an OS over remote disk, but how often do you really need to do that? The one time every year or two that you do, just start it before you go to sleep and it will be done long before you wake up.
Well I guess if you already have an external drive you wouldn't need to ask whether to buy an external drive?
Problem is, always need it when they're all closed.
Just got taxes done, acct. handed me a cd. No more paper copies they told me. Don't feel comfortable using remote disk w. such sensitive info. Just call me old fashioned, or just old.
I think for $100 a usb powered superdrive in such a svelte enclosure is money well spent for just such instances.
A flash drive should do the trick too. Much cheaper and so small that it is more in line with the idea of the Air. And I do wonder why you would go with a machine that is basically wireless only if you don't trust wireless security.
And would your account REALLY have REFUSED to print things out for you if you insisted? How many pages could it be? A few? A dozen maybe? Might cost $0.50 or so? I mean they DO have printers, right? Doesn't sound like good customer service to me if this is so.
