Ok one thing I wonder:I wonder how happy microsoft is about the prospect of people playing directx titles without necessarily owning a windows license.You "port" a PC game to OnLive and it gets sold to OnLive clients. However, the OnLive platform runs on Mac OS X and Windows, and soon, independently on your TV. At E3, OnLive demoed it running on the iPad.
Mac OS X users now get access to a ton of games that they wouldn't have otherwise. If OnLive creates a Linux client, that will be even more dramatic: Linux users who traditionally are lucky to see a AAA title per half decade would suddenly be treated to a buffet of games.
