My China made keyboard had a sticky key (Right arrow) key, so I called IBM to request a new one...
I got the Thai keyboard and after setting it up, these are my comments:
1. It has different feel to the keys. For example, they are not as bouncy as my old one - This is the first thing I've typed, so it feels weird
I guess the keys don't travel as much...But this is a good thing I guess...
2. It has a more solid built to it, however, I still had to put a bit of foam on the right side corner to avoid minimal flexing...
3. The mouse stick feels better - I think the one in the old keyboard was broken, as it kept drifting...
4. All an all, a good replacement...I would recomend it over the china keyboard...
