Got my SP4 i5 256GB 8GB Ram this morning. I have to say I'm disappointed. This is my first windows tablet experience and first experience with a high pixel density screen with windows.
I think the hardware of the SP4 is superb. No complaints there. As the previous poster noted, windows Hello works great. My disappointment is with windows 10 itself as a tablet OS. It seems the app development is very poor even for what I would call CORE apps.
For example, the MAIL app is terrible. When composing an email you can't push a button to add a contact to the TO list. When viewing email, it does not display emails correctly with inconsistent text scaling and image scaling as well as background colors/images not working. Sure I could just go to the website and just view and write email there, but that defeats the purpose of having a tablet PC. I may have well just purchased a traditional laptop (Not what I was looking for).
I have a huge issue with scaling in general. I don't know who app/program developers are writing for but it must be for people with the eyesight of Super Man. Everything is super tiny and when I boost up the DPI even CORE apps don't scale properly. How does Microsoft expect developers to scale their apps when even they can't do it correctly.
I would go as far as to say the Quality of apps for windows 10 tablet is much much worse the android and I think android apps are much much worse then IOS apps.
Anyway enough ranting about the software aspect of the SP4. For hardware everything seems really fast and smooth (ignoring poor apps/programs). One thing I noticed on the hardware side tho is when I am downloading something (not using a lot of CPU) the tablet gets really warm with the fan on full. Anyone else observe this on theirs?
I also forgot to add, the track pad on the typecover is good except when I do 2 finger scrolling it feels like there is a delay like I have to put 2 fingers on it then wait a second or so before it realizes that I want to scroll.
