Coupled with software for scanning your fingerprints, both the Victorinox Secure and the Victorinox Presentation Master are
designed for and
fully compatible with the latest Windows 7 OS, Vista and XP (as long as you're updated to Service Pack 3). The downside here is that Mac and Linux users aren't supported
at all - even without the fingerprint functionality (it sure wasn't fun getting to the press kit stored on the drive).
This issue should perhaps be stated explicitly on the packaging, if not altogether rectified, as we tend to assume at least some degree of universal compatibility with flash drives and this could make things unexpectedly difficult for users switching between platforms at work/home/school/other.
