Similar situation here ...
Last Tuesday, I went to Best Buy to pick up a Surface 3... it was incredibly appealing for $500. Quad core Atom, 4GB RAM, 128GB SSD. I was looking for a Microsoft Office tablet.
After spending about 6 hours installing patches, firmware updates, etc. I was able to get Office installed and really start to use it.
I was pretty excited at first, especially for what I paid... it seemed like a pretty capable device. My experiences with it declined at an expoential rate and it was returned two days later on Thursday.
Lessons learned:
- Windows 10 still doesn't know what it is. Using it strictly as a tablet OS with no keyboard or mouse (only a stylus) is still very painful and unintuitive in many areas. It's clunky and inconsistent. I think Microsoft did a commendable job improving over Windows 8, but mostly for desktop users.
- Palm rejection, even when switched to "left handed" mode, sucks. My palm was marking, panning, etc. making my writing/drawing experience incredibly frustrating.
- The Surface 3 was released on May 5th, 2015. Even with all of the updates installed, it was still incredibly buggy, had driver issues causing blue screens, and also randomly "black-screened" - requiring a 5-10 second power button press to force power-off. It crashed on me three times (blue screen with some sort of power state driver error) and black-screened on me twice. In 24 hours. Google searching and forum reading indicate the issues were common with no known fixes yet.
That was enough for me... I had no more patience left to discover all of the other issues I'm sure I was destined to have with it.
I bought a silver iPad Pro 128GB Wi-Fi, Apple Smart Keyboard, Apple Pencil and Apple white silicon case. I couldn't be happier. Everything just works. I was a little worried about the Apple Smart Keyboard, specifically when it comes to stability on various surfaces like my lap. I'm typing this with the keyboard on my lap right now with no issues. First impressions are fantastic, though I will admit I am probably duped a bit by "The Contrast Effect" right now based on my experience with that joke of a whatever it thinks it is Surface 3.
