I got one a couple months ago. It's more than adequate for my use- browsing, mail, Office, and other light to moderate tasks. Even with lots of Edge tabs open the RAM never gets close to maxing out, and I haven't noticed any CPU strain.
Other than minor light bleed on the bottom edge of the screen, as reported by lots of users, its build quality is very good. The light bleed doesn't really bother me.
I really like the fanless feature, by the way.
I only have a couple bug annoyances, and they seem to be reported for all versions. If I change the Surface orientation from/to portrait/landscape with Edge open it may freeze. It always happens when I do that and resize the window going between tablet and desktop mode. I have to restart with power+volume up.
The other annoyance is the windows in tablet mode don't stay maximized, hence the comment above.
Both are fairly minor and I expect eventual fixes.
