1. It won't be long before some genius protective third party case maker has a nice case with a stylus holder available;
2. A real smart third party case maker will "fix" the ridiculous way that Apple charges the "pencil" by building that capability into a protective case. I'm thinking it'll just be a simple adapter and cord built into the protective case. (Hmm. I should probably file for a patent for that right now.)
Beyond that, it's going to be interesting to see the comparisons to the Surface 3 since Microsoft Office apps run on iOS now.
A $10 cord makes the charging easier.
The Apple Pencil can be fully charged in under 15 minutes. Not too much of a risk, I think.
