I voted 'yes' as an older gamer and one who is disabled and can't walk too far, this method of purchasing a product is by far the best for me.
I purchase a lot of games on line and up until a week ago (when Broadband came to the Scottish countryside) I would tick the burn CD option and wait on its arrival
However, I share some of the concerns over lost Key's, damaged downloads etc but I have noticed that some Digital Distributors offer a 'download insurance' that enables you to obtain the product again, if the worst should happen and you lose your original.
As a Semi-retired Indie myself, I can see the posibilites of this form of delivery and anything that cut's out out the middle parasites can't be all bad
