You might want to check the OP - there is at least one exchange.  While there's no Mac wallet (because we cannot find anyone with a Mac to compile a wallet and the people that we've contracted with in the past no longer do wallet work), there is a Windows wallet, and source code for all of the varieties of Unix/Linux.

As for wallet updates - I keep asking but nobody answers:  If you want an update, what do you want to see done differently?  The wallet and infrastructure works, we have exchanges and pools.  If there's something you want to see, speak up!
