I had a chance to try out the Surface Book a few days ago and I thought it was pretty great (I was just testing out the sketching capabilities) in the Fresh Paint app.
The only digital sketching I’ve done has been on an iPad Air with a Pencil by FiftyThree. The best part about the sketching on the Surface Book for me was the pen’s familiar shape to a real pen and its sharp accurate tip. Something I hadn’t known before is that you can replace the tips of the pen with different shape and friction level tips. Initially, I thought it sounded a bit gimmicky but quickly changed my mind when I saw that they sell this kit of 4 different tips for $10 which seemed pretty reasonable to me. It’s really cool to have those different options and if I had one I would definitely want to try them out.
As someone who already owns an ‘older’ iPad, I really wish you could use a Surface Pen across platforms!
