I've never had a keyboard phone fail
A beer spilled on my Treo 650, killing a couple of keys. I was able to buy a replacement keyboard off a random eBay seller and swap it in without much trouble (after which the phone was as good as new), but it was an annoyance all the same.
I suspect a newer touchscreen phone would've been less vulnerable to that kind of failure. Can't say that I've tested the theory yet, even though I usually have a beer in one hand and my phone in the other (to log the beer) whenever a beerfest is on.
