The bad -

Dock Lock: The first unit I received had such a flimsy lock that the keyboard would not stay docked with my Visor Neo. I tried tape, but it was only partly effective and makes removing the PDA for Hotsync difficult. And for the price, one shouldn't have to hold the thing together with tape! On advice of Fellowes customer service, I exchanged the keyboard/case for another. The tiny lock is much better but still prone to disengage occasionally, so I must ensure it's still latched before I turn on the PDA. Customer service is also sending me a shim kit that is supposed to help the Neo fit more snugly.

Stylus: The stylus (still needed at times) is cheap plastic with a poor feel, but the PDA's much nicer one is inaccessible in this case. The stylus conveniently stores in the back of the case, but this prevents the case from lying completely flat, so typing is sometimes a little bouncy.

Keyboard: At the most, two fingers can be comfortably used for typing. Since the left side of the case is thicker than the right which contains the keyboard, using the left hand is more difficult because it bumps against the side of the case. I have yet to find a use for some of the buttons.

The good -

Sturdy case.
Quicker, more error-free character entry that with Graffiti (at least for me).
Useful enough to be a keeper despite its flaws, but I'll keep an eye out for the next generation.
