XO-1.1 differences

[Sridhar Dhanapalan]

A year ago, we deployed about 200 XO-1.1 machines in a community. I'm
not sure if that version number is official, but it's what we call
XO-1s with XO-1.5 style capacitive trackpads.

I am going to that community in a couple of weeks to upgrade them to
the latest OS build. I only have the standard XO-1s available to me
for testing. Is there anything peculiar that I need to know about the
XO-1.1s that will affect development and testing?
