Our Cisco network guy uses a USB to serial adapter to connect to all of the Cisco gear in our office with his laptop and it works just fine for him under Vista.

I agree with that, I usually try to get the real part before I go to adapters. With a serial port it may be very difficult to find on a new laptop with one though.
If you get a laptop with an expresscard slot or something you can get an adaptor... expresscard accessoris do not stickout as much as usb adaptors.
otherwise, you should problably look refurbished.
