For those who don’t own a Blackberry, and your cellphone doesn’t come with a nice QWERTY, you can always pick up a Bluetooth 2.0 keyboard, to enhance your productivity for typing on your cellphone.

I-O Data has got a mini Bluetooth 2.0 QWERTY here, which its size is small and portable enough to let you bring along with your cellphone. Anytime, when you stop by at a coffee shop or at any place that you can lay the keyboard down, you can start using it to type all your lengthy messages.

The I-O Data Bluetooth 2.0 keyboard connects to your cellphone similar to any Bluetooth devices, just turn on the Bluetooth connectivity of your cellphone, and they’ll then be paired up and you can start using it to type all your words.

The price of this Bluetooth 2.0 keyboard isn’t cheap, which costs $153 and hits stores in Japan only, next month. It’s better to put the money towards a phone with full QWERTY. But the little difference is, although the I-O Data keyboard is small, but you will still be able to lay all your 10 fingers on it to type like a computer’s keyboard. Whereas a phone comes with QWERTY will only let you type with two thumbs, which shouldn’t be as speedy as typing with all your ten fingers.
