I prefer the thinkpad keyboards myself and use a mechanical keyboard on my desktop (one which I consider to have the best tactile feedback available: a Topre Realforce).
However, as a dvorak touch-typist I was curious to find out just how well different keyboards performed, so a while back I did a 1 minute random word test on each and got (approximately) the following results:
#1) Topre Realforce: ~110wpm random, ~140wpm non-random
#2) White macbook (island style): ~98wpm random , ~120wpm non-random
#3) Thinkpad T420: ~90wpm random, ~110wpm non-random
I used this site to do the comparisons: http://speedtest.10fastfingers.com/
Would be interested to see what other people get.
I bought both an 87UB (the $400 one) and a 103UB, and kept the 103UB because I both prefer the feeling of it over the 87, and also discovered that I like having a 10-key again. Had pretty much abandoned them.
...all purely subjective, of course, but i just prefer the typing experience on the 103 to the 87.
- looks stylish
- very cheap to manufacture
Obviously the manufacturers wouldn't switch arbitrarily, but I wouldn't be surprised if those two reasons alone weren't enough to drive the switch.
I prefer them for that last point alone. Non-chiclet keyboards get filthy and are a nightmare to fully clean.
It's also cheap - Rs. 1500 ($30)

For me, one of the biggest factors in choosing a keyboard is if it has a right control key directly under the forward slash. I use the key to the left of the A (Caps Lock on my ThinkPad) as my left control key when a key chord involves a letter on the right hand side of the keyboard (e.g. C-u in qwerty), but I still use my right control key in chords whose letter is on the left side of the keyboard (e.g. C-a). I've considered trying to get used to using the left control key all the time to preserve my right pinky and to faciliate the adoption of new keyboards (e.g. MacBook), but I'm not there yet.
I do agree the ThinkPad keyboards were the best in its class.
