Congrats! Please share what you think of it when you get a chance.
I love it so far, but I haven't really done much with it other than install apps and watch a few YouTube videos.
When I was going through the initial Windows 10 setup I thought there was something wrong with the screen because the brightness was fluctuating a lot, but it was because it was set to automatically adjust to the room brightness.
My biggest concern is the battery life. I have a Surface Pro 3 that seems to only get 3 or 4 hours per charge (if I'm lucky), so as long as the Surface Go does better (hopefully 6 or 7 at least) I'll be happy. The battery estimate shown in the taskbar is pretty much as inaccurate and useless as it is on my Pro 3 though.
I like the keyboard a lot. I just got the less expensive black version. I will get a pen eventually too.
The screen size might take some getting used to, but the bezels don't seem quite as thick in person as they do in videos.
I plan to try running Photoshop on it soon. Haven't taken it out of S Mode yet.
