Hello,
I hate Windows 7 because of the lame USB transfer speeds when using a flash drive. No, it is not my imagination, it's well documented on the internet. Some flash drives work fairly well, some delay a transfer of 2 gigs or more by 5 extra minutes...
That being said, I found a couple of good drives and wanted to let you know about them.
16 gig Mushkin Mulholland flash drive - Good transfer speeds and no crap software on the drive.
16 gig Corsair Voyager USB 3.0 flash drive - Rubber coated and slightly larger than a regular flash drive, this one is my fastest by far using the 2.0 interface.
