I do most of my work on my tablet. It's much more portable and convenient to do all my sketches and many of my illustrations on my tablet. (I rarely use paper and pen anymore). I work mostly in raster drawing on site, preparing preliminaries etc. I use the photo editor in Corel often, but there's no app for a tablet so I have to wait until I'm back in the studio to do what I need to do in Coral. If I am in my studio, I often need to quit drawing, upload my sketch to my laptop, do what I need to do and export it back out to my drawing application. This is very tedious and time consuming.
