i, for one, was impressed at how the software authentication system went so smoothly when i used switch device wizard in DM and it transferred masterdoc over to my new pearl.
@ first start-up on the new device, it re-authenticated my purchase rights and i got an email with my new PIN and password for use with efile desktop. sweet.
on the opposite side of the spectrum, i had to nag handango & beiks to change my PIN so that i can activate the dictionary i bought for my new PIN. that took like 4 days....
