Hello everyone, I'm new to the forum. Every starbucks or coffee shop I walk into. I see ipad users using Amazon.com: Kensington KeyFolio Pro 2 Removable Keyboard, Case and Stand For iPad 4 with Retina Display, New iPad (3rd Gen) and iPad 2 (K39512US): Computers & Accessories this keyboard. Has anyone used this? It's a bit more expensive than the average ones. Please tell me how you feel about it and if its worthit.
