I have been a member here long enough to see that most members are trustworthy and honest. So I want you guys to give me your opinion. I like my Surface Book. It's great, it works great and it really stands out. But I found myself not really using it as a tablet. Sometimes this is because it has a poor battery life as a tablet, or because it is a bit of a hurdle to get it out remove the keyboard, store the keyboard while holding it in a small train seat, opening it, then having to plug it back to the keyboard because sleep mode can drain the clipboard battery etc. Moreover, I find myself reaching for the keyboard most of the times and while it is great and the trackpad is the best, I miss the fact that I really got myself a laptop that I intended to use as a tablet as well but find myself that the form factor restricts me from really using it as a tablet. My major concern about SP4 is battery life. I have read a lot regarding battery life of the SP4 in this forum but I still can't get an accurate picture of how much battery life I can get with use of office, edge and drawboard, cause these are pretty much what I use most times, except during the evening that I use it to watch movies. I would also like to know how the keyboard cover compares to the Surface Book keyboard as I use it a lot for writing.
