Absolutely agreed! Its tiny! Very silly design (and thank god I'm slightly colour blind, because the brown is aweful!)
Moving your finger over to the OK button tends to move the pointer around, so its awkward even with mouse sensitivity set to minimum.
The menu button is the more logical for select, but I'm not sure that the template logic will allow such context sensitive actions? Also, it would then stop you being able to click straight into the menu from the media or vol/light options.
