Hello, I just bought a Surface 3 128/4 model. Here are some questions that I have: 1. Are there any cases that you all would recommend? 2. When using a case, will there be any overheating issues since there are no fans or vents? 3. Is the Surface 3 just like a "regular" tablet? What I mean is I am coming from a Sony Xperia Z2 tablet and I had a case on it from the beginning and never had any problems with it. 4. Can I use a USB Ethernet hub for internet connection? 5. Can I use the micro-USB port for file transfers, or is it strictly for charging? 6. Can I use any ol' Bluetooth keyboard, if I wanted to use a keyboard? I am sure I had more questions, but I forgot. I am sure they will come to me after I post this lol. Thank you in advance for any and all help!
