One of the reasons why some people prefer using their Blackberry devices is due to its physical keyboard layout, which some might argue is superior over an on-screen keyboard. Some Android manufacturers might have acknowledged that fact by putting out smartphones with both on-screen and a physical keyboard, but Apple has remained firm in their resolve in sticking with the on-screen keyboard.

However if the iPhone 4/4S has enticed you with its operating system and features, and all you need now is a physical keyboard to make it the perfect device, Concord Keystone has announced the Keystone ECO Slider that attaches to your iPhone 4/4S and features a slideout keyboard for all your texting needs.

It pairs with your iOS device via Bluetooth and comes with a built-in rechargeable battery. The battery can be recharged via micro USB and supposedly will be able to last you a good 30 hours before requiring a recharge. While it does add on a bit of bulk and thickness to your iPhone 4/4S, it is a good solution for those who must have the feel of physical buttons under their fingers. Head on down to Concord Keystone’s website for more information.
