Quick Sketchbook paint

I find Photoshop really slow to use...I can't remember any of the hotkeys, and I never remember any of the brushes I like, so I end up trying all of them any time I switch to a new brush. Not to mention all of the stuff that I have to search through to find the few simple tools I use all the time, and all the buttons are so tiny, despite my 20/20 vision, I still have trouble finding stuff! Any way I prefer Sketchbook for drawing and thought maybe with the brushes they have, I wouldn't need to use Photoshop. I was wrong... I don't mind it for doing quick studies, and I'll always prefer it for storyboarding, but the painting is better in Photoshop. End of rant.
