Need help on G-70

Hi all,
I am eventually going to try out a G-70, but I've got a question here. If the G-70 hasn't the latest OS, which I think is 1.06 would I miss anything if the keyboard is not upgraded to it? Would thinks sounds better? Many thanks!

If you're going to a serious dealer the G70 most likely will be updated,
if not they might do it while you're there.
