Some people will ask what should I choose a Bluetooth or a 2.4Ghz keyboard?
In fact, it isn't hard to make the choice.
They are both wireless connection without a doubt. And from all reviews you are able to find on google or forums, Bluetooth is more reliable on connectivity than 2.4 Ghz, and easier to connect than 2.4 Ghz. In a word, Bluetooth is the best choice for wireless.
However, on price section, 2.4Ghz is cheaper than the Bluetooth.
