Hmmm, well the reception has been interesting.
homer: Have you ever tried Gamefly, Netflix or iTunes? Owning physical media is becoming obsolete. The new models are "services". Instead of paying $$$$ to own a few, you pay fewer $$ to be able to use many. Owning the physical media has inherent risks and limitations. Aside from potential damage to the media and/or the console, there's also misplacing it. And generally the convenience factor and reduced TCO of using a service makes it well worth it. I certainly felt the way you did when it came to DVDs. I switched to NetFlix because I figured it was less cost and I'd only buy DVDs that I really wanted to add to my library. Now most of my DVDs sit unused in a container because everything I watch is through Netflix.
A_C_E: just like all consoles, there would need to be an initial library. You say developers wouldn't go for it. I wouldn't be so sure. There are many positives for them. No piracy. Continuous revenue stream. No distribution costs. Ability to fix problems after release without major expense. Lower cost to develop. Marketing would not need to be focused on a major campaign, it could instead be spread around and extended due to the extended life of the product. All of those are major selling points to the people who run the companies.
All: Look up "disruption strategy". Yes, it is not a top of the line product, but it is an adequate one that provides high value for low cost. I think it fills a niche demand, solves problems with the current system. As the user base grows and more people become "online consumers", the amount of funds going to the developers who risked it first would get larger and larger. More developers would want a piece of that growing revenue stream. I think that follows the disruption strategy well. It's positioning the company in a place where the people will be in the future. Netflix disrupted Blockbuster. They are in a very dominant position now and going to be harder and harder to beat. All they were offering was "old movies and some new" for a very low price. Nobody would want streaming videos, the quality sucks, right? Well, looky looky where the market is going...and Netflix is already there with their product in many devices already in homes and an ever growing subscriber base.
