- There is no game compatibility information. When I buy a console game, I know that the game will be compatible with my system. There is no such guaranty with Steam games. I would like to see a simplified benchmark tailored to pre-made Steam Machines so that consumers can understand how well they'll play their AAA games.
- They lost momentum with the SteamOS platform, and many developers are now skeptical of porting their games to Linux. The Steam Machines were supposed to be launched one year ago and with them their Linux platform. Some developers took a big investment to port their games to Linux and fight around subpar OpenGL drivers. When they were done there was no Steam Machines and they were met with a Linux userbase of just 1%. Now, I believe, we'll only see more Linux launches once the developers trust the Steam Machines as an established gaming platform.
