Counterpoint from anecdote, Sir: I just had a hard drive fail, losing all the related media (unless I wanted to pay three times the cost of the not-inexpensive drive to recover it, at any rate) completely. I have few problems with digital games, but it's the same reason I still buy books in between buying digital ones--I want things on my shelves, I'm not one of those needlessly "efficient" people who are burdened by the 12 seconds it takes to change a disc, and, when the hard drive carrying the games fails and I can't recover them, I'd like to still be able to play them on a new drive. Admittedly not the strongest case, and the latter argument is more against things like install number restrictions and DRM, but neither of those are going to go away, and losing the ability to uninstall a copy of something means I'm permanently one short, and being one short can add up quite quickly. I can buy a game or a book, in its physical form, and I *own* that object. The underlying stink about Microsoft's presentation was the loss of consumer ownership in favor of licensing, and the sheer volume of outcry, and subsequent relief when Sony said they would allow the consumer direct ownership of their purchases, is very evident that whatever form it takes, people want to own what they buy. Only in media does this show up. If I bought a dress or a nice suit, I don't have a limited number of times I can wear it before the company asks me to buy it again. If I buy a car, I can drive it to my heart's content, neglecting it or meticulously taking care of it as I see fit (as long as I pay it off, of course). At no point does the manufacturer say I need to buy the car again because I've hit 60,000 miles.
There are books on my shelf that have been read so many times that they've needed repairing. There are games I have in disc form that have been uninstalled and reinstalled so many times I'm pretty certain there's a permanent data imprint on the various drives and equipment that runs them. I would love to see a world where I can do that with all my digital media, but as it is, I have to closely monitor these licensed issues to see which ones expire or only allow so many installs before requiring a new purchase, and which ones can be treated like a physical disc. To go all digital in and amidst this storm of ownership debates and DRM debacles would be like trying to fly with wax and feather wings off of a skyscraper--you might have a decent idea, but the execution is severely limiting, and end result might be more damaging than if you had waited and properly prepared.
