Ah god damn it. This already exists, It's called wireless HDMI and it works perfectly fine today. Just hook it up into your desktop, then your TV and then you have steam on your TV without moving the gigantic box.
It costs way too much as it is now. I'm not going to spend $150 - $200 for that.
Most people just want to play PC games, just the vocal ones are dicks about it. I don't think that expecting a game to run nicely is asking too much. They can say all they want that they're not doing a good job, but that doesn't really excuse anything. If you're a programmer and someone is paying you to do a job, telling your boss that you're working hard but that you aren't doing a very good job is a pretty great way to get fired. The analogy isn't perfect, but they aren't charging 'not a very good job' prices.
The point isn't that anybody cares about the 30 plays limit. The point is that it's hilarious that Nintendo decided to do that. Nobody who can buy their own games is going to play a demo 30 times. Nobody. On the other hand, someone who only plays demos is NEVER going to buy the game. They played a demo 30 god damn times, they obviously don't want to spend the money, they'll just find another demo.
I don't start most of my retail games more than 30 times!
