Will I be able to watch my stuff in the future?

['thul]

yes. it is a good point there... 'thul recently tried installing the old computer game "warcraft II" on a win7 64bit computer, and discovered that the remnants of DOS required for it to work had been removed... only through using an overly complex set of modifying programs that 'thul barely half understood could they get it working...

There will always be a few around the world capable of showing/using the older stuff, but as time moves on, they will be further and further between, and it will get more and more expensive to get such converted...
