Also got an X250 when my X61 died (actually, the battery died, and Lenovo
no longer sells replacements, and the aftermarkets el cheapos last maybe
10 cycles before dieing).

I like the conveniece of the touchpad, but ended up disabling it because I
kept getting false triggers from letting my palms rest on the palm rest.
Key to getting the trackpoint mouse buttons to work is to configure for a
ps2 mouse rather than defaulting to the fancy imsa mouse (or whatever its
called, google it),

Similarly, the function keys default to volume up/down and the like,
requiring holding down the "Function" key to get F1 to F12. However, there
is a magic key combination (doesn't anyone read the docs anymore?) to lock
the Function key function so default is F1 - F12 and you need to hold down
the function key to get mute, volume, etc., just the way it used to be.

My biggest gripe is the lack of indicator lights for key statuses such as
caps lock, AC, and low battery.
