<p>My old Pentium 166Mhz had two USB ports; these devices are far more pervasive in computers. Unless the university you are attending uses 486s, a USB flash key should suffice.</p>
<p>A warning for Mac users: I do not know if this applies solely to the Iomega Drives or to Flash Drives in general, but deleting items on the drive (by dragging them to and emptying the trash) does not permanently erase them from memory. I do not know why.</p>
<p>I was able to confirm this flaw by plugging the drive in a PC and noticing how all the files I had, from the day I purchased the drive, remained unscathed. </p>
<p>I do not know how to fix this problem without formatting it; and that too, one must format it on a PC (to FAT32) in order for it to be cross-platform compatible. If one formats the flash drive on a Mac, the drive will not be accessable in Windows.</p>
