Time to consider USB2

I didn't notice that my laptop comes with USB but not USB2 when I puechased it. Actually it'd been too late when I recognized the fact as I came to NZ soon after I bought the laptop in TW. I can't replace it with another model in NZ, can I? Normally usb works fine to me for normal use, as the data in my thumb drive (Transcend 128MB USB2) is not that big and the waiting time is still bearable. However, it takes rediculously long time when it comes to backup my big bunch of data into 1.3 GB removable media (Fujitsu GigaMO 1300U2). Who can stand waiting for more than half a hour (or sometimes 1 hour) for backing data up (especially I'll use it more frequently in the near future)? It seems I really have to take it seriously to get a USB2 adapter for my laptop. Therefore, I make up my mind to get one in the town tomorrow, without knowing that some big problems shall come after that.
