Compiler warnings should never be ignored. If you ignore them, they build up and eventually obscure things like: "Unable to resolve reference to x as it was built with a higher framework version". This is just a warning, but try and publish such an application and you will quickly find it does not work in production. The number of times I am asked to help someone solve an issue which they could have solved themselves if they just read the warnings...

It has a soft pad on the bottom why would it scratch the screen? And by the way, I'm on Code Project... my art is code. I probably wouldn't need a surface dial, but I know a lot of folk who will love it.

Oh, you're one of the people who hate Microsoft... my mistake. 1. Tools like the Surface Dial have been around for a long time. This just adds some additional features to it. Some of which may very well be extremely useful although, obviously not for you. 2. If you are clumsy enough that you can't use it without having your fingers touching the screen you probably aren't a great artist. 3. Elbows are rejected just the same as palms. Especially when you are using the pen. 4. $100 is not unreasonable for the thing... overpriced is your opinion.

Erm... never heard of "palm rejection"? It's been around for a while on a lot of touch screen devices.
