Lately my OQO has been locking up. It locks about 3 times a day.
I had a problem with freezing when I installed SP1 for Vista. Had to do a forced power off shutdown and reboot every so often. MS support suggested I start trouble shooting with msconfig by turning off everything in the startup tab, and under services, turn off all non-Microsoft services. To my surprise, I discovered all I needed to keep on was OQO Services, the WWAN service, and OQO Manager. I was still able to use and control all 3 radios! Even though it looks like you may be turning off BT or IDT, you really are not. All you lose is the systray icons. My BT keyboard and mouse work just fine, connecting and disconnecting when appropriate. (Since I don't use the tablet feature, I don't know the effect of turning it off.)
