Hi, I tried out windows 10 on my surface pro 3 for a day. I found that it was always running really hot, and I noticed that the battery life was really bad. I enjoyed many thing with the program. I liked the fact that we are given an opportunity to swap between RT mode and desk top when disconnecting the key board. I think I like the new start menu in desktop mode, though I unlike so many of the people out there who complain about 8.1, I really like it. I find it works very well on the surface pro 3. I personally can't understand what people complain about. With window 10, I really liked the fact that I could keep adding desktops and swapping between them, just like on my MacBook pro. I am also looking forward to Cortana though it is unavailable in Australia. Because of the heat and the battery life issue I changed back to Windows 8.1, though I ended up with a corruption and had to wipe and reload 8.1 factory issue. Anyway, it was an interesting experiment, as is this trial run of the surface pro 3. I really enjoy this machine, though I still like my Mac. I am not really stuck on any brand, I am a bit open that way. Anyway, I am looking forward to greater things with Windows 10, and from my surface pro 3 in the future. This said, I will be waiting for when the wrinkles are ironed out.
