Difference between Port Replicator 2 and Mini-Dock

[xcrunner51]

I'm not quite sure what justifies the $100 price difference between the mini-dock and the port replicator 2, don't they essentially do the same thing? am i missing something?

If I'm not mistaken....the mini dock has 4 USB ports and a key to lock your thinkpad....while the replicator II has only 1 USB port.

That sums it up well. With the port rep II, you have to fiddle with a kensington-style lock to secure your machine.
