One other thought - am I the only one that hates the pens that OQO sells to use with the 02? They kind of have this fine texture on them, which in principle should make them grip well, but in practice I find as slippery as heck. I have taken to using one of my leftover tablet pens from another device.
I have no problems with mine, I quite like things plain and black and the default pen fits the bill, and the texture is just "pen like"
