Will any bluetooth keyboard work?

Most BT keyboards work without issue I've found. I'm currently using the Apple mini BT keyboard with my Nexus 7 without issue!

 

I've just bought a Bluetooth Logitech tablet keyboard for iPad and it works just fine on my N7.

The Android versions of this keyboard were much more expensive on Amazon.

I'm very pleased with it.

 

I have the eXo mini-bluetooth keyboard. It's rechargable and even has a laser pointer built in and a touchpad. Got it from here Amazon.com: eXo Keyboard: Computers & Accessories (ticks me off, it's $10US cheaper than when I got it, LOL)

This works like a charm, although being so small, thumb typing on it takes getting used to. With the touchpad and Fn keys it's a Godsend. I use it with the Citrix Receiver app to access my company infrastructure and the soft keyboard is a bit, ummm, undeveloped on that app.

I connect to projector to run PPT presentations. Last one I was at, there were 3 of us doing presentations. The first two brought their laptops, I didn't. When they were done and my turn came, my boss asked if I needed time to get my laptop and set it up. Just smiled, took N7 out of my jacket pocket (already to go), set the projector to wireless receive, connected with N7 and started the PPT. Using this keyboard's laser I got through my presentation with flying colors, no glitches at all, N7 receiving bluetooth signals from the keyboard and sending wireless signals to the projector.

Afterwards my boss congratulated me on the PPT's "perfect timing". She saw my puzzeled look and said the screens on the presentation were so perfectly timed, they seemed to switch on their own. She didn't even know I had a keyboard, thought this thing was just a laser pointer. LOL

Anyway, loving it. No regrets, no problems. And recharges with standard mini USB.

 

Use a Zagg Flex keyboard. Works well and nice thing is it has dedicated Android specific buttons that some keyboards may lack.

 

I am using the HP Touchpad keyboard, and while some of the webOS buttons don't work, the essential stuff works great.

I've been using the above keyboard, it acts as a case and a stand. It's perfect for when I'm going to meetings and I don't want to lug around my laptop.

I know it might not be big enough for everyone, but I have chubby fingers and I rarely have a problem with it. When worth the 20 bucks.

 

I have a khomo case /keyboard combo. Works great looks good, and rotates to hold the tablet in portrait or landscape mode.

 

This is the one I use. The nice thing about it is that it has a pull-out touchpad. The keyboard is compact but still feels like a full size model for typing. No finger gymnasics required. And Motorola builds good quality.

 

Bluetooth is a standard so, at least in theory, any Bluetooth device should work with any other Bluetooth device.

I have a number of Bluetooth devices such as keyboards, mice and speakers and they all work with my Android devices, N7, phone and mini-pc. They also all work with my Windows based machines that are Bluetooth enabled. I haven't encountered any Bluetooth devices that work on one device but not another.
