I never liked the chiclet style keys, however they have impressed me recently. I got a call from my sister who was crying because she spilled about a quarter of a bottle of water in the keyboard of her first gen Core Duo Macbook, it wouldn't get give a ROM startup noise or show a screen, but the power cable still lit up blue on the magsafe connector. I popped the HD out and saved her data, I took the upper half (keyboard and track pad) off, and noticed that there was not a drop of water inside, they keyboard has some sort of rubber under the keys or something. This prevented any water of the large amount from hitting anything internal. It's actually a good design.
I am in the process of checking every nook and cranny inside to see if there are any droplets, but it's looking good so far. I have the board upside down with a fan flowing through it so we hopefully don't have to buy another upper half.
We will see, Jess
Update: I guess one of the ram sticks is bad or got wet, I pulled it and the machine booted fine, the keyboard even works too, going to leave it out all night to dry though.
