We haven't seen any difference in lag time with the Pro memory (Sony
brand 512MB). It does format much quicker (big deal), and transfers
to the computer are marginally faster (~20%, using USB2.0).
I'd say if transfer speed is important to you, and you have USB2.0 on
your system, and/or you need more than 128MB on a single stick,
then Pro is probably worth it. Otherwise stick with regular sticks :-).
