I have one that says A1197 on the bottom, and MB111ZM/A on the box. Don't know if it's new or old, but it has an all-white body (no grey buttons). It's wireless.
I've had some issues with right-clicking: if I wake the notebook up from sleep, sometimes I can't right-click until I go to mouse preferences and expand the right combo-box (even if I don't change anything). Is this the same problem as the old one had? Should I get a replacement?
TBH, I like the grey side buttons more. And I don't like the massive gap between the side buttons and the rest of the case. Apple products don't usually have holes in them.
