This is one of the very few Poker sites that has downloadable software for Mac OS X. The software used to be slow, but they've managed to get it good. My only real complaint about the site (mainly the free side) is that in no-limit tourneys, sometimes half the table goes all-in on the very first hand before the flop. When playing for free, I guess it works out every now and then in the long run but it gets very old after a while. This is pretty much the only site I would risk money at.
