Well, to depend on OnLive or any other rental is like to depend on a hooker for sex. In some respects it might be preferable to a permanent girlfriend or a wife - no need to worry about hooker's needs or health, how happy she is and such. But even in the Universe with the abundance of available hookers I would still prefer to be totally sure when and from where my next sex will come from. It is far more convenient to me, that's why I am all for the girlfriends and wives.
BTW, OnLive IS NOT like Steam. On Steam you can play without internet connection, and you can download backups of your games, and install them if necessary. Steam is just one of the digital distributors. OnLive is not, it is a market alternative to brick-n-mortar rental outlets like bankrupted Blockbuster. I guess as an opportunity to check out a game that does not have a demo for free it is good, but I wouldn't shell out any money on OnLive.
