Will I buy the Surface Pro? Probably not: I have the SP4, i7/16GB/512GB. To me, it looks like too little improvement compared with the one I own. Still, I'm curious...
* 50% increase in battery life... SP4 said 9 hours of video playback. But what is reality?
-- My first use of the SP4 in December 2015, the battery went from 100% to 15% in ca. 2 hours: I did what I do now -- participated in web discussion fora.
-- Since then, my experience is that *in real life*, the battery life has varied between 2-5 hours, depending on use, firmware upgrades, etc.
-- A couple of weeks ago, I had the *shocking* experience of "burning down" the battery from 100% to 20% in 45 minutes: I ran computing intensive Python scripts in rapid sequence.
* So: I'm curious as to the *real life* battery capacity. Of course, I like what I hear about "instant on", no battery leakage in sleep mode, etc. Again, I'm curious as to what testers find.
* I just stayed a few weeks abroad, renting an apartment with wi-fi. Wi-fi worked fine on my Lumia 950, but I was not able to get any decent connection with the SP4... if I opened Edge and typed in an url, perhaps 5 minutes later, the web page showed up... impossible to use. In a cafe across the street, the wi-fi worked fine also on the SP4. Any improvements with wi-fi? I'm curious about the LTE model.
* I may get hold of one of the new type covers -- I "hate" the plastic surface of the original type covers... after 5 minutes, it feels like my hands are sweating and sliding off the keyboard. But I don't need to upgrade my SP4 to get the keyboard.
* Pen... does the new pen work with SP4 -- and give 4096 levels of pressure sensitivity? Or does the improvement require some new processor in the SP (2017)?
* For an upgrade, I might also like to see 32GB RAM... OK, it would be monstrously expensive, so maybe not.

An alternative to me (running computing intensive programs) would be to have a "home" workstation and the possibility to remotely log into the workstation using some SP (2017) or something and just use the SP as a terminal/word processing tool. To have stable connection, the LTE version would probably be necessary... I am quite disillusioned wrt. wi-fi and the dream of stable connection.
