Why install it on a public machine at all ? (Score 1)

It seems to me that there is really no use to installing GDS on a public machine, especially one in an internet cafe. Surely the point of an internet cafe machine is that you go on it and use the internet, maybe sending some email. You don't expect it to remember you when you come back or keep all your email, and many cafes reimage the machines every day anyway to keep them clean. In such circumstances, what benefit does GDS give you ? Simply put - GDS may be very cool, but if its not necessary for the task, why install it ? As I side note, I have it on both my home machine and my work machine (which only I use) and its wonderful. It really is very very good indeed.
