My Sp3 was great today I took my Lenovo laptop, opened it hooked it up to wifi when I first got to the meeting room then put it away (incase I needed it). Got out the SP3 and used that for the entire meeting taking notes etc. It did annoyingly decide to have a fan blasting session for the first hour or so, it wasn't that noticible due to half the other people in the room either using macs or work-issue Lenovos with their fans going, but it was annoying me so I had to check it out as it's unusual for my i7 to do that (yes I did say it was unusual for my i7 to do that). I traced it to Bitdefender which was a bit odd, tried uninstalling it and got a "repair" option so did that and after it restarted it was then as good as gold but that first fan session cost it quite a bit of it's battery life... however even so it still lasted the entire session with constant screen-on and notetaking, sometimes web/email checking etc.
Oh and I'm still on my original battery in the pen... LOVE it for this sort of thang.... no one appeared to notice the device, it was quite unobtrusive propped in portrait mode on my lap/rested against the table in front instead of acting like a barrier like the other laptops were. It also connected to the guest wifi with no issues either..
