I get why you typed all of that out the way you did on a site like this, but it's unfortunate that you feel the need to almost apologize or say things like "one of those people" to make it sound like you feel iPad users are inferior or something.
I'm typing this from an iPad Pro 12.9 and I am someone who frequents this site because for years I have wanted a Surface Pro to replace my iPad, and every time I've tried one of them (I've bought SP2 through 4,) I end up returning them/selling them as I just end up disappointed. My personal opinion is unless you are someone who absolutely N-E-E-D-S the things that a Windows PC can do that an iPad can't, then there's really very little reason to own a Surface Pro beyond some kind of Apple bias. If you want a very functional device in a tablet form factor, an iPad just has a better user experience, apps that work far, far better in a smaller/touch screen interface, and obviously much longer battery life.
A Surface Pro is a laptop that just happens to look like a tablet, an iPad is an actual tablet. I've tried so many times to like a SP as I would like having a full on PC in a tablet form factor, but as I've said I just always end up disappointed. If I had never used an iPad, maybe I'd be ok with it. But even without the comparison of iPad app ease of use vs. Windows 10 trying to be tablet friendly and failing, like you stated these things just seem to have constant issues with basic things that you don't want to deal with in a device such as this.
They're great looking devices, and like I said if you are someone who absolutely positively needs what a Windows PC can do in the form factor of a tablet, then I understand why you own one. But if you're of the mindset "It would be cool to have a PC the size of a tablet," you just may end up being someone who is frustrated by the shortcomings. I fully understand that an iPad Pro 12.9 costs just as much as a SP and that the SP is capable of more, but for me personally, the extra things it's capable of are just not worth the trade off of much worse battery life, less reliable, and just not as pleasant to use for the relatively basic things I use it for.
