Anybody using PixelMator in Snow Leopard OS X?

I like the idea of PIxelmator…I like how you do things…seems to be like a Shun knife to Photoshop’s broad axe…

but I’ve read negative comments about it…slow performance, RAM hog, and it offloads onto the graphics card, which is bad for people with cards that have little RAM.

Can anybody report whether these comments are true/still true?

I’d be using it on an 8-core Mac Pro, but I’d like to know that the app itself was fast; not just relying on my hardware to make a brick fly.
