Am I right to be really scared about what Apple will do with the ATV and the iTunes store?
I have the feeling they are going to do something to a) gimp the 3rd Gen box (which I have no issues with) to force us to buy the new one and b) do something to the store to screw over all the purchases we already have a c) disable the iTunes Share feature so we can no longer stream our custom media from macs to the ATV. I will be so pissed if they do any of these things.
I'm heavily invested - I have 2 ATVs, 350 iTunes Movies, 30 TV Shows and my entire Blu-ray/DVD Collection of over 2,000 Disks has been ripped and meta-tagged to work with iTunes. I would NEVER forgive Apple if they f'ed with the service at this point. Especially if it's only done to force people to buy new, crappy hardware and sign up for their even crummier cloud/subscription services.
I can relate.
I am heavily vested too in regards to iTunes and movies ripped for it, not as nearly as much as you, but starting over right now would be a royal pain in the wallet amongst other things.
