Honestly, for me its one of the greatest improvements for paintings now without the gappy drawing. And now the paintings save a lot faster! How great is that?
I think it's great! although it is difficult to find a color that you previously used (the color blocks are kind of tiny) but, I shouldn't complain. It's a great improvement.
I like painting, but i haven't been able to paint with the new one because my DSi's internet isn't working and the paint feature doesn't work on computers, which I'm using right now.
