Steam

[Bolivar]

If they don't go away in 5 years, they will certainly change into something significantly different (not simply a dedicated portable gaming device that only plays portable games made for it).

They've already made that change, though. The 3DS has Netflix streaming and probably a lot more to come in the future. The Vita is essentially a tablet. And the PSP has been a great MP3/video player, as well web browser and comic viewer for many years now.

Also, I just wanted to add that this guy tweeted that "Steam is a much more closed platform than PSN. Yes, I was surprised too." Not putting it out there or using it to say anything, I just thought you guys might find it interesting

Overall I think this discussion has read its course, good exchange, guys!
