Linux is easily the worst (well, at least Ubuntu and Mint) with respect to Bluetooth pairing and remembering it for me. I use a multi-device Bluetooth keyboard to switch between a Windows laptop, Ubuntu laptop and a MacBook Pro almost daily. So when I tap the button in the keyboard to switch, it takes 5 seconds to connect (if it connects) on Ubuntu, almost instantly in Windows, and couple of seconds on Mac. And Ubuntu laptop cannot do wakeup from sleep with Bluetooth keyboard or mouse even with tons of tinkering with the /usb/devices/*/power/wakeup conf and in /etc/rc.local and /etc/init.d.
