I want to play Diablo 3 myself, but I just don't have the money to afford it, right now. I enjoyed what little bit of the open beta I was "able" to play, but, the open beta did harbinger the potential inconveniences of the always-online requirement. The stories I've been hearing recently of the connection and server issues definitely makes me think twice about buying this game, at the very least waiting a few months for the issues to be hashed out before taking the plunge.
I agree with Jim that, if I pay $60 for a game with the expectation of being able to play it, then I damn well better be able to play it and not be locked out from the game due to bullshit technical issues that could have been avoided by design. However, my response is not to complain or get angry; that is a waste of my time and energies (being older, you get a lot more conservative about how you use those things). My response is to simply not buy the game and move on to something else. If the game companies want my money, they're going to have to stop with the shenanigans and try to have a quality product with quality customer service. I am the customer, and they are supposed to please me, not the other way around. If game companies are not going to try to provide quality products with quality service for the money I pay, then as far as I am concerned, the entire game industry can just go out-of-business; I really don't give two shits. I'll find other things to do, more productive and fulfilling things.
EDIT: Just to waylay any miscommunication with the above, obviously, the game industry is in no danger of actually going out-of-business; however, I would not be surprised to see the big publishers eventually fall to the smaller studios that don't pull all this BS. I expect an asteroid to hit the industry, one day, and wipe out the big, lumbering dinosaurs, leaving the more adaptable, smaller creatures to thrive in the aftermath.
