IPad pro with pen support.
/case closed
Case re-opened. I have an Apple Newton (mid-1990's) with pen support. Apple introduced the iPad Pro with pencil support; it's way more than a stylus which Microsoft doesn't have.
/case closed in favor of Apple
I bought an electronic pen for my iPad—which has had pen support for the last five years—at the last MacWorld in San Francisco in 2013 and which I have been using for two years. I just threw away a magnetic keyboard with full stroke keys for the original iPad last week, which I long ago passed down to my daughter, which she no longer has. I found physical key covers awkward to use as I had to find a flat surface to place them on and they did not really work as a laptop. . . and I've tried several, some with built in kick-stands that pre-dated the Microsoft kick-stand. /Case Closed.
Yea, a pen for fine detail work, art, photo, CAD... Not for basic functionality of the device itself.
