I'm wondering how buying the service would work, do you buy a game for $50 and you play it whenever? or do you rent it and can play for a short period, or do you just pay a flat rate for the month, and you can play any game that they have. Because if the latter is the case, I don't think the industry is going to be helped out in any way if you never have to buy a game again.
On topic, I probably wouldn't, for awhile at least until I see if it works and I have a faster internet connection.
