When FINALLY getting Windows 10 to work in a dual-boot system, I discovered that the updated driver for my trackpad contains Remote Link Support, which allows me to control my laptop using my phone! Bluetooth won't connect to my Blackberry in 10, but after updating the touchpad driver in 8.1 (which requires uninstalling and reinstalling) I was able to link my Blackberry to it and then pretty much completely control the system.

I might not use it as much, but it will be awesome when I have my laptop hooked up to a tv or something. Also gives me an idea for interface methods for my hypothetical HTPC project (Remote-Link or similar with a Nintendo WiiMote for touchscreen-like control)
