I would like to sketch directly into emails using my pen and touch screen.
I often sketch simple diagrams to suppliers when it is more expediant then writting lots of text. Presently I open MS paint and make the sketch, save it, then paste into my email. It would be much easier just to have a paint surface in the email itself. To extend this editing existing embedded images in the email thread woud also be useful for collaboration.

I would like to add an adjunct to this in that Microsoft needs to add a powerful graphics design / editing platform if they want to really capture an audience. Having to spend hundreds of dollars on a competing product just to have a separate powerful graphics design / editing platform is sometime outside the capability of small companies, and sometimes not approved in larger companies.
