If anyone cares - I actually went out and returned the iPad pro back case, and bought the urban armour UAG one. It has a pencil holder, and allows the apple Smart Cover to be used. It holds the pencil very well and secure...so that's one issue solved.. While I was there, I compared the SP4 to the iPad pencil, and yep - the iPad pro has less of a glass feel, and is more natural to write with. I was pretty much set on returning it, until I tried goodnotes, which single handedly won me over. I tried notability and PDF Expert, but goodnotes seems to have the pencil implemented much better. I was able to also import huge PDFs into goodnotes, so I can make annotations directly on it, and the palm rejection is perfect on it..so another issue settled. I spent about 2 hours out with the wife, studying...and the writing is fantastic. One thing I really like, is how with split screen you can automatically switch from window to window with the pen..you don't have to register a tap in the window first, before you can write,,like the SP3. So I pretty much did a 180. If goodnotes is any indication, I think the iPad pro will be an amazing device once everything gets implemented.
