You can hold down function and tap left arrow for home, right for end, up for page up, and down for page down. It also has a delete key, and holding function while pressing either scroll lock or pause emulates insert. I don't use insert at all, so I don't know for sure which key is which.
The original model has a full USB 3.0 port, a USB C 3.0 port, headphone jack, mini HDMI port, and a Micro SD slot. I think the newer model has all of the above except the Mini HDMI is replaced with micro HDMI.
I have the original model with the Atom X7-Z8750 CPU, 4 GB RAM, and 64 GB storage. If you don't need the extra storage, RAM, or processor, go for the Win. It's much cheaper and will work beautifully for the most part.
Having said that, I'm experiencing a few weird issues with mine. The computer shuts down after about two minutes if you put Windows in sleep mode. I have to boot it from scratch then ext time I use it so I've resorted to having Windows hibernate when I close the lid. My internal microphone no longer works and I can't record audio from any application with any audio device. I suspect this one is something in my Windows installation. Finally, the computer restarts when I tell Windows to shut down instead of powering off. I have no idea what this is and it's incredibly irritating!
