I tried the Linux beta yesterday. It looks very promising, but there is not much going on yet.
Yeah it is still work in progress and most likely will be until beta release. Hopefully by then basic transactions will be able to be performed. I plan on starting out by offering free notary and arbitration services as well as selling products.
and of course I also plan to buy products too. I want to shift as much of my commerce on to OpenBazaar as possible.
