Anyone using SAI?

Tweet

Hello myLotters! I've always used Photoshop to draw and colour all my art (I've tried OpenCanvas too, but only for linearts, I like Photoshop better when it comes to colouring), but lately I've been hearing a lot of good things about another program called SAI. Apparently a lot of digital artists use it and they say it's really nice. I was wondering if there was anyone here that had tried it and, if so, what's your opinion of it? Thanks in advance! :)
