As I said before
I said in a previous post prior to the release of the new mac mini that I thought Apple would go this way. We all don't download our music or movies. Some of us like to have a physical product that allow us to rip music to our Macs etc, and play in our car etc. We also like to watch our movies on different mediums. Alot of us want to install software that we have only on disk and not have to pay out for more 'Stuff' just to be able to do what can already do with existing equipment.
I don't see the lack of a drive as an advancement until the whole of the UK has superfast broadband where we can all watch and download movies via the web, (my speed is okay so I am not a grumpy old git ). I just see the situation as an expensive box of tricks that looks good but one you add additional equipment makes the whole thing an untidy box.
