Lenovo ThinkPad X201 vs. X200 Tablet PC

I currently use a Lenovo ThinkPad X200 Tablet PC. It's not old, but it's also not the new ThinkPad X201 Tablet. What are the differences between the X200 and the newer X201 Tablet PCs?

First, the new X201 uses the  Intel® Core™ i7 processor while the older X200 uses the Add up to Intel® Core™2 Duo processor. The i7 is currently the "best" Intel processor on the market.

The new X201 tablet also features a multitouch touchpad (in addition to the TrackPoint pointing device).

I'm waiting for Lenovo to install a keyboard light on their tablet PCs. The include an LED light for their laptops, so why don't they add the LED light feature for their convertible tablets? That's on the top of my wish list right now.
