Well, my first off my testing here is going to be a bit different than most of my other work. I can't exactly benchmark a keyboard and case, so I'm just going to run down how it was to use, because that would be what you're interested in hearing. Well, the case size was annoying, but it wasn't impossible to carry around with me either. I'm always wearing a jacket of some kind around, and it fit just fine into one of those pockets.
Next test, the keyboard: The rubberized buttons on the keyboard were comfortable enough to use, and the overall layout was pretty familiar as it is a pretty standard QWERTY keyboard. The response on the buttons was quite effective and pleasing to use. So, as far as feel there goes it was pretty good. However, it was far from perfect. Due to the fact it is inside a case, they keyboard is restrictive to say the least. They have the whole keyboard in about the same width as most people are used to having for the ASDF keys on their keyboard. While for me this wasn't an issue, someone with larger fingers might easily run into trouble when messing with it, as the keys are definitely on the small side.
Another thing with this that was kinda cool was the fact that it has no battery anywhere in it to replace. I don't want to spend more money on batteries than I already do, unfortunately that means that it has to get power form the Palm. This did noticeably shorten the batter life on my palm. I suppose it is easier to change my Palm's AAA batteries than it is to spend a fiver on 2 stupid watch batteries that most small things use.
Last bit here is protection, which it did very well indeed. I gave the case a few decent tosses to see if it'd hold up and protect the palm from normal drops. I wasn't about to throw my PDA 20 feet to find out how good the case is, because I don't feel like dropping it. However, from a good 6 feet plus, it did just fine. A few scuffmarks, but nothing you wouldn't expect, and the Palm survived 100% intact.
