When you first see the new Logitech K780 Multi-Device Wireless Keyboard ($80, £75 or AU $150), it's obvious that it's the big brother to the

The K780 is bigger -- it has a full-size keyboard that includes a numbers pad and had an integrated slot for holding up a variety of smartphones and tablets, even the 12.9-inch iPad Pro. It also features dual connectivity for up to three devices, so you could connect to your devices through the Logitech Unifying USB receiver or Bluetooth (translation: you can have the keyboard connected to your Windows or Mac PC with the Unifying receiver and use Bluetooth with your tablet or smartphone).

Sounded interesting, so I called one in to test in advance of its launch. Indeed, the K780 is bigger and while it's pretty slim, it's significantly heavier and sturdier than the K380 and really is designed to be a true desktop keyboard.

I like the way the stand has been integrated -- it's hard plastic that's covered with a grippy finish, which helps keep smartphones and tablets from sliding around in the slot.

You can connect up to three devices to the K780 and toggle between and toggle between them using the numbered EasySwitch buttons. The keyboard is powered by two AAA batteries and there's a spot in the battery compartment for storing the USB Unifying USB receiver. Logitech says that with a power-saving idle mode and an on-off switch, the K780 Multi-Device delivers up to 24 months of battery life. That's quite good.

The responsive keys are larger than the K380's and well spaced out. I used the keyboard for an afternoon and liked typing on it. I want to use it for a week before posting a full review, but my initial impressions are quite favorable, which isn't surprising considering that I'm a fan of the K380.
