Not that I am planning on buying one, because my x201 works fine.
Here are some things that I feel about the line myself.
Item 1:
It would be nice to be able to turn off the touchpad. My x201 does not have a touchpad at all by customization choice. From what I understand, the touchpad is standard now. I still prefer the trackpoint. When I play with one of my relatives Thinkpad Edge, I get annoyed when my palm triggers off mouse pointer movement.
I do not see anyway this can be fixed through software or hardware other than being able to turn off the touchpad.
Item 2:
Component Indicator lights are nice as include option. Going back to the Thinkpad Edge, which has no component lights for the hard drive, wifi, and bluetooth. It would be nice to have the option still available. I understand that there are some battery and hardware cost saving to not include them at all. Maybe it can be an option on the website store, because it does come in handy when I put my laptop to hard work. It just shows me that the laptop is still working well, when the software does not provide indicators of its own.
Item 3:
Thunderbolt Technology & USB 3.0. The number of ports to provide is optional.
Item 4:
Docking stations are nice.
Item 5:
VGA, DVI, HDMI, Displayport, and Thunderbolt Again. Displayport only seem to catch on for Macs, which does not seem to use full size ports either. I guess what I am trying to say is that displayport monitors are not very prevalent in the United States as least. I understand that at one time that displayport was the plan. It does not seem to me that it worked out in practice though.
Item 6:
Thunderbolt one more time vs Expresscard. I think that originally will say Expresscard's ancestor PCMCIA was created, so people could use a network via cellular technology addons in addition to network card addons. Basically, these things at that time were not included in the laptop. USB 2.0 ports is also an example of something that came out later. Today it seems to me, Thunderbolt and Expresscard have a new meaning now. In addition, I would say that either one is directly related to how much hard drive space you have in some fashion. Having a low capacity (less than 130GB) hard drive would probably negate the need for high speed external devices in a practical fashion. Windows programs usually are installed to a local hard drive of the machine. Running Windows programs from removeable devices probably would not work out for every conceivable program that could be installed. Anyways, Thunderbolt due to form factor with a good hard drive would probably not be a bad idea.
Item 7:
Black color is still a nice option.
Item 8:
Keep the backup and restore software is a must. I have not found a better one that is included in a laptop.
These are a few of my favorite things.
