I actually feel quite strongly on this issue, I actually have a backup of this keyboard on the off chance something happens to it and it’s not fixable. I’ve actually had to disect my keyboard at least 2 times to clean it after pepsi incidents 
Infact… if i could bring my keyboard to work and not look like a freak… i probably would.
In my humble opinion… there is nothing better than a Fujitsu 8729.
Well, all those little buttons feel really, really rough when you…oh, you meant for TYPING…my mistake:o
Actually, I can’t stand those “natural” keyboards; there is nothing natural about your elbows sticking out when you are attempting to type. I make more mistakes on those…
I like the keyboard that came with my Gateway computer and the Microsoft Internet keyboard. Nice STRAIGHT rows of keys and they click along nicely when you’re typing. I tend to type faster on noiser keyboards than on quiet or soft touch keyboards too.
Goldtouch. It’s infinitely adjustable!
I’ve used an Apple Extended USB keyboard for 3 years on my Win2k/XP machines. Love the feel - only downside is that the Windows driver does not support the ‘print screen’ key - have to use the “On Screen” accessibility keyboard.
Volume control/mute keys are neat (but now available on many keyboards - not so 3 years ago)
Has anyone used one of those flat, rubbery, spillproof “indestructible” keyboards
My roommate has one, and it’s about as awful as can be expected from a quarter-inch-thick, rubber keyboard. The keys are very shallow, and have a “mushy” feel. The edge of each key is rigid, and there is presumably some sort of a plunger in the middle to make the keystroke, so your finger seems to sink into the key as you type. I’m normally a 90+ WPM typist, but I can barely hack out a sentence on that thing.
The old Gateway 124 Anykey keyboards that Gateway used to ship are the most dependable and comfortable I’ve ever used. I’m typing this out on the 12 year old one I got with our brand spanking new 386 sx 25 in 1991…
You can still find them on eBay for less than ten bucks… just search on ‘Anykey’
Usram. Just an idea, but most folks use their fingers when deciding on keyboard feel. 
Yet another vote for the IBM M style keyboards, they are perfect in everyway: excellent noise, great key press feel, heavy enough that they stay put and don’t clatter around when you are typing fast, and in a pinch they can be used in self defense, as either a club or for stopping bullets.
Right now I’m using an older Compaq keyboard that is acceptable, it’s heavy and has a good feel to the keys but it’s not as noisy as the ‘M’ but it works.
As far as laptop keyboards go I absolutely love the feel of the keyboard on my Thinkpad. Being a laptop and all the key press is much shorter and it is qutie but it still feels really good to type on. I guess the folks at IBM just know how to make a good keyboard
