If they are dropping 10btc a month on promos, why on earth do we not have a working client 13 months after the old sealwithclubs closed? It's clear that their player base needs something other than a broken windows client in order to be able to access the site. Windows is the 90s, most people use other OS's now. I can't be bothered to install a bunch of virtual machine software on an arm9 in order to try to run windows just for some poker. It's better to just do something else.
LOL, 85% of all pc and laptop users use windows.

But of that percentage they are still losing the chunk of players who were using browser version of pokersoftware.....not to talk about the ones who used to play from their smartphones and tablets
...and let me add the last consideration: in bitcoin world (where seals operates) I guess that those percentage (OS usage I mean) should be really different if not almost inverted.
