Latitude E7240 with pointer stick?

Hi,

I am looking to grab a used business class laptop. I want an 11-12" laptop and it MUST have a pointer stick. I've seen on eBay that the 7440 and 7240 seem to have the same keyboard. Does the E7240 have the connector to allow the use of the pointer stick? If so, I can just buy a keyboard and swap. I am guessing no, but am looking to find out if I can get an E7240. (I'd rather get the Dell as I have tons of AC power adapters for Latitudes). Otherwise, I'd have to look at a Thinkpad.

Thanks,
