Throw in a Blu-Ray drive in that Apple TV and I may consider buying it.
I have a hunch we'll not see BR in anything Apple any time soon, if at all.
It appears technology is moving away from physical media (be it some flavor of compact disc, hard drive, etc.) and more toward content delivery - much in the cloud computing/push content vein.
We're seeing this in iPhones & iPod touches: devices that, in conjunction with an app like Simplify Media (whose functionality I suspect we'll see in an eventual iTunes update), can remotely access iTunes Libraries via wifi (or 3G). Rendering something like a massive/more expensive 120 GB iPod a bit irrelevant when content can be delivered wirelessly to cheaper, more efficient device.
We're seeing this in the MacBook Air: a device that no longer includes an optical drive.
We're seeing this in content providers like the Netflix (and similar services): where content is streamed to devices, never once requiring any physical storage space for said content.
It's fairly clear to me that Apple not only has a firm understanding of these concepts, but are actively moving in that direction - whose side benefits include less waste.
I don't own an TV (yet). And I find it refreshing, if not long overdue, that Apple is openly seeking feedback form TV users. It's no secret may feel this device holds immense potential. And understanding what the user wants/expects is a positive step in providing the user that experience.
All in due time, I suppose.
