I disagree with most of the people here, windows 8 DOES game very well, I have yet to find a single problem with gaming. So far, TF2 works, Chivalry works, BF3 works, medal of honor works, minecraft, and every software I have downloaded (even ones only advertised for windows 7) except avast antivirus. Most of the people here don't know what they are talking about, and probably just need to update their drivers if they "can't run anything on it."
Not to mention 90% of the people that complain about it have not even tried windows 8. Windows 8 does NOT remove the start button, it just has a new GUI, and if you don't like it, then download free software to get it back.
For the people saying that it cost more, I got my windows 8 for $30 less than the equivalent on windows 7, and if you already have windows 7, you can upgrade for $15(if you recently purchased windows 7)
You can also get ALL the apps for the windows tablet in the store, so if you like tablet games, you can play them on your PC.
Even if it is buggy(which I don't agree with) it will become the standard OS for developers in a short period of time.
