I have an iPAQ h5450 and the Record button sometimes turn on my h5450 and sometimes not.
So sometimes, if i want to record a voice memo i have to first start my pda, and then push the record button. But sometimes i only have to press the record button to record.
I agree - the trick is NOT to press one of the two volume directions and press firmly in the middle. Mine is set up to launch Nevo, but I'm probably changing it over to the new @Mail program! But in either case, it always starts my PPC.
