I noticed that on Windows 7 RC1 the Arduino 16 drivers do not work (at least for me). It is easy enough to download this (http://www.ftdichip.com/Drivers/CDM/CDM%202.04.16%20WHQL%20Certified.zip
) driver package to be able to connect the Arduino to your computer on Windows 7. I just would think that with the Windows 7 release coming in 3 months and the amount of users using the RC1 already (it has passed the number of Linux users already) that we would want to have the new drivers. Unless Arduino 0017 will come out before then I just think the drivers should be updated.
