Well its nice to say it's "almost" Arduino compatible, but to anyone buying one, the concept that library authors don't get paid to update their library's isn't going to occur to them until they discover something doesn't work.
And even then it's not really their problem, if they believe its Arduino compatible thats something of a global declaration with no visible conditions attached.
I was about to place an order for 10 to play with, but now it looks like it might be best to wait for a Wiki page to make an appearance.
