A:AnswerI find the keyboard on this 16" model to be very comfortable to type on. It is in no way cramped. I don't know how it compares to the keyboard on the 14" model.
A:AnswerThank you for your question about this HP OmniBook! Yes, you can purchase a stylus pen for it: Make sure that it is MPP 2.0 and Best Buy sells those in the store.
A:AnswerI am not a techy, so I don't know what an EMR tech stylus pen is. It does support a "Bamboo Ink" device, which is a separate purchase. I have not used it yet, so I don't know how easy it is, but I do have an Apple pen for my iPad, and suspect it operates the same way.
