No problem. The only "inconvenience" now is that Windows Dial-up networking doesn't have usage tracking, I'm on a basic pre-paid data plan, so it would be nice to know the last re-charge date and total data usage. But that's not a major problem as I can always login to the service provider's site to check.

Btw, Windows 7 driver is totally new, not an update from Vista driver, so you need to uninstall the Vista driver to avoid conflict.
