@Sidetopic: Yep, there even was a CD version of Secret of Mana in the making for this SNES-CD-Thingie and in some parts of the game, you notice, that something is missing (some orbs for weapon upgrades to the max f.e.).
@Main: Amazon managed to establish their eBook-reader due to lack of proper competition (Kobo still has its flaws) although you need Calibre to make it a bit more open,
I see no reason why they shouldn't be succesful with this. The Controller looks like function over form style and if they manage to get the software right, their big consumer circle may buy it, although I think, that the Steam machine will take a lot of the market share in the future, because it already has an awesome catalogue of games and an innovative controller that actually seems to work.
The times were gamers need a shelve or wardrobe for their collection is over anyway, appartments in the west get smaller and more expensive all the time and since you need to register and download console games or parts of it now too, the differences are getting incredibly small.
