The major negative I see with that keyboard is that its yet another separate accessory, I need to carry. Unlike other solutions like the ASK that attaches to the iPad, I need to carry this. Speaking of which, it makes using it in mobile situations a little more cumbersome - at least that's what I'm thinking (having not used it )
I was really impressed with the look and design, but you bring up a good point and given how it attaches to the iPad, will it fit on it, if I have a case on the iPad?
Good to know, I was trying to discern how much more thicker it is.
I think people already stated the advantages of the ASK, and for me those are important.
No batteries, it gets it power from the iPad
Attaches to the iPad
Can be used on the lap, many BT keyboards are completely separate and its cumbersome to have a keyboard and iPad on your lap at the same time.
Overall, the ASK provides a great integrated experience, BT keyboards offer a different set of advantages, I like the idea of thin, integrated solution that I don't have to worry about batteries.
