Oh yes, I would if it was possible.

hossie is correct, there is example:

It is also kinda funny how when you buy a car you can actually return it if it is not working as expected, but try reading any software agreement - you are using it on your own bloody risk even if you pay a pile of money for it. How come?

Nowadays it is a good move in IP world to release a crap soft/movie, spend 90% of budget on advertising and even if you are unsatisfied you can't return it. Usually you can't test it either. I'd want to get my money back for over 80% of movies I actually saw in last year if I would in fact bought them.

As soon as software will be sold as service, I will consider paying for it.
If angrybirds (as an example) was subscription based paying per time I played it, let's say 10c per hour I would really consider that - if game is crap you don't pay much, if it is great you pay for the fun you had. New level pack released - more time played. That is somehow fair at least, just doesn't work that great for movies

p.s. debs are there on rapidshare for example, so I wouldn't claim you can't find it on interwebz.
