I've a little question.

Lately I've been expending a lot of time in the computer, and my back is starting to pay the price. So my doctor told me to take work out of the computer, use my tablet to read and replay emails, and that kind of work.

I work as a part-time pixel artist, so I was wondering if Photoshop Touch has the options to, say, work in good quality pixelarts?

I know it has layers and brush-tool and it can produce beautiful CG graphics, but what about pen tool, and pixelart style graphics?

I'm tempted to go for a Surface, but it might not be cost efficient, so I was thinking on going for a good tablet with a good couple of apps that let me work some pixelart illustrations and design, that I can later take on the PC to actually animate them and give them the final touches.

Any experience here with mobile/tablet apps regarding pixelart?

Any comments are welcome!, and please, excuse if I misplaced the topic location.
