Multiple pairings might be frowned upon when it comes to spouses, but no one's going to complain about Logitech's new K810 Bluetooth keyboard, which can pair and easily switch between up to three devices at once. And despite the slight hit in battery life, night owls will appreciate the fact it comes with backlit keys that self-adjust to match the room's ambient lighting.
But thanks to a built-in sensor that only powers up the keyboard when your hands are close, its built-in USB rechargeable battery still boasts around ten days of life between charges. And when you couple that with a brushed aluminium body and keyboard shortcuts optimised for Windows 8, PC users finally have a nice alternative to Apple's Bluetooth keyboard. Even if at £90 you're paying a premium for glowing keys.
