I start university in September and looking for a portable USB flash drive.. I don't need anything too big in size, so I'm looking at some of the smallest they have in sizes, like an 8GB. My only question is, will this USB drive work correctly on both Mac and PC's? without having to format them etc? as I have an external HD and a PC doesn't recognise it. Also, USB 3.0 is out now, but that won't work correctly in all computers yet, right? so I assume the computers at the university, being outdates, they don't work? I've seen this one below, anyone used this brand before? Kingston 8GB DataTraveler Thanks..
