A:AnswerNo. It's not a Bluetooth keyboard, although you could hook one up. I have the original surface book. There would be no point really. the screen wouldn't stand up on it's own without the keyboard. In Tablet mode it does have a virtual, on-screen keyboard, but it's not really great for typing. But the hardware keyboard is AWESOME with a very, very good touch pad. That keyboard is the main reason I'm going to purchase a Book 3.
A:AnswerThey claim 17.5 hours. I have used mine for 3 hour stints and it drops to about 60% so I only estimate 10 hours, but I was doing some photo editing and CD burning. I would imagine longer for your described use.
A:AnswerThe RAM is soldered into the motherboard. However, it's possible to upgrade the SSD in the device. Although doing this can void your warranty, so it's not really recommended you do something like that.
