The Keytech keyboard itself is pleasingly thin.
It's FANTASTIC to have proper cursor keys.
The onscreen keyboard hides itself, giving you much more screen space.
Makes the iphone 4 much more businesslike.
Battery life is actually only a few days, not the 45 days claimed.
The keys feel cheap - but still way better than the on-screen keyboard.
Each time you use the keyboard, you need to press your first letter several times to wake it up.
It's a bit boring to have to charge both the iPhone and also the Keytech.
The charging LED and bluetooth LED tell you nothing at all and the instructions don't explain what they mean.
The iphone doesn't always turn the screen around to landscape (why oh why?) so sometimes you're typing uphill!
It'll never happen as Apple is so contrary, but I do hope the iphone 5 has a physical keyboard...
