I also used PS Touch only because it had some color, and contrast adjustments that none the others did, but it is mainly for photos. LayerPaint, LayerPaint HD(more suited for tablets), Cloverpaint, Artflow, and Sketchbook Pro. Here are the top painting apps for Android if your still leaning towards the Hybrid. On the go it only runs Android which then you are using only the limited Android apps. Plus a slightly above average monitor which would be larger, and would also have better color accuracy and contrast levels(even the standard Cintiq line has this issue, although they have improved a little over the years). 13' is fine on the go but at home it's way to small.
First it is too small for it to be a primary workstation, as when connected to a computer. The problem with the Hybrid it that for me it fails on several levels. I got mine refurbished on Ebay for $550, and it has similar specs to the Surface Pro 2 but with an 11.6' screen.
Now with my Ativ I am using Photoshop CS6 and couldn't be happier. The apps available on Android are too basic. The Note is fine for sketching and doing roughs but that's about it. I have a Note 10.1 which I just replaced(about a week ago) with an Ativ 700t running Windows 8.
