I tried it out for about 10 minutes last night, and that was enough for me to think "WOW!" its really cool.
Yeah, I tried it out last night myself. I thought the same thing, looks pretty cool! I guess it's been a LOOOONG time since I used ANY paint program(insert memory of Deluxe Paint 4), because I was mostly lost :-o When i finally figured out a brush effect I was pretty impressed :-) This will probably be a purchase soon, because it ran quite well under UAE.
-edit- Before anyone asks, i partially used M$ paint to make my avatar, but I hardly consider M$ paint a real paint program, it's a toy.
