Right now I'm just using FullTilt and
pokerstars, sometimes I test another poker sites but I use to play frequently just FLT and PokerStars.
I use ubuntu 9.10 64 bits, and Sun VirtualBox OSE ( Open Source Edition ) running a windows XP guest just for poker purpose.
Some sites has java clients that runs well on linux like NoIQ Poker, for example. But I could not find anyone with a full linux client. Tried to contact support teams and the answer is allways the same. " We do not support linux OS at this moment."
I think this is a big mistake since many linux users are also poker players.
The first
poker site running a full linux client will fast achieve a wide set of users .
