While we can use our smartphones and tablets for sending messages or posting tweets, if we want to type documents or emails, having an actual keyboard makes things a lot easier. This universal keyboard works with any Bluetooth-enabled device — Windows, Android, or iOS. It allows you to instantly flip your tablet or phone into a tiny laptop computer for fast, comfortable typing. After use, you can easily fold it to save space and reduce clutter. With a rechargeable battery, this keyboard lasts up to 48 hours of use. Touch screenwriting is terribly slow compared to using an old school keyboard. This could be a lifesaver if your regular laptop has problems.
