What makes "older" Thinkpad keyboard superior to T

[DesertSilver]

I've heard in various threads that people think the older Thinkpads have better keyboards. I'm wanting to know your opinions on what you think makes them better than the T6x keyboards. I'm a new Thinkpad owner (my first laptop ever is a T61) so I don't have any previous Thinkpads to compare to.

I'm asking this question geniunely; I'm not trying to start any flame wars, just asking for your individual opinions.

I asked this in a separate thread about a different topic and got one response but wanted to create a specific topic to get some responses.
