So, some SteamOS questions.
Will non-Steam games run on it, without having to hack the OS? Minecraft, for example, runs natively in Linux. It would be a small disaster if that type of game couldn't be incorporated, whereas I think it's less likely that Origin games will run.
How many users will get to play each game bought on SteamOS? On current gen consoles, I can play games with as many profiles as I like. It would be a travesty if games bought through SteamOS where locked to an individual account (yes I know, FamilyShare). Personally I think this is what will be changing with tomorrows announcement. O+O = Multiple Devices.
How close will Valve and their partners get to the $400 price point? For all his posturing, Weaste does have a point. The PS4/XBOne could look better value for money in some peoples eyes, if the hardware is cheaper. Of course the counter argument would be that, with Steam you are getting better value for money with the games; a huge game library to buy already and a huge game library you may already own. Then you have to look at 2nd hand games (not going to be on Steam unless the EU or various nations demand it), and steam sales. What is really better value.
