I have a couple of quick requests, if you have the time given the many other requests!
1) We've never heard the final weight of the keyboard. It would be great if you could provide us with the final weight of the tablet, the keyboard and the charger (incl. cable)!
2) Could you check the battery wear when you receive the device and when you return it. Ideally, it'll be 100% for both. (you can use "powercfg.exe /batteryreport" or one of many hardware reporting tools)
3) If you happen to have Win10 Pro, it would be great to know whether you can enter a pin for bitlocker using an on-screen keyboard. Note that if the machine comes with Win10 Home (as is probably the case), it's won't be possible to test it.
Many thanks and enjoy the prototype!
