Mine came in yesterday!!! Wow the 15" is perfect. I love the 3/2 screen format for reading, programs and OneNote. Yesterday I installed all my programs and had no issues with anything. Overnight I downloaded a few hundred GB of my OneDrive data. I got the loaded version with a TB of storage, 16 GB or ram and the NVidia 1060 GPU. I had the first SB, I liked it but it had some problems, I sold it and have been using a Dell XPS 15 which I will probably sell.
I will say the clipboard doesn't seem to be much different as it still wiggles back and forth when you move the base around and when you tap on the screen but for me it's not much of an issue. The machine screams when you run programs, for instance loading an AutoCAD file is almost instantaneous and it loves the NVidia graphics card. The Wi-Fi seems to be faster at my house, for instance OneDrive when downloading use to be around 8mbs and now is downloading around 13mbs. The screen is great. Battery life so far is not the 17 and 5 hours advertised. I know I running the screamer but it looks more like 6 and 2. Yesterday I used the clipboard for just 2 hours and it was almost exhausted - even so I am still loving this machine.
I also got the new pen and mouse and they are both pretty awesome. I haven't used mouse on more than one display yet but I can see this being very useful as I travel all week and the less I have to carry the better. As a matter of fact I also carry around a new IPad Pro 12.9 which I have been using as a reader, a note taker and for entertainment, this is also going to be sold. This new SB2 is great.
