Apparently Plants v. Zombies is available on Steam for only $10 rather than the $20 that it costs on Pop-Cap. Having played the demo I really enjoy the game, but I don't want to pay $20. I'd go for $10, but then I am reminded that Steam doesn't have an OSX client, so outside of running bootcamp or something, I will have to pay more to play games. This should be part of a windows commercial.
