Not sure about that, but here, there are not many Unix user although, I suspect there are still around.  Most had migrated to using high end PCs and server type,  and some linix (correct spelling?), which are much cheaper.. Linix, because of open source... no licencing issue.. but also limitation.. too.. but quite useful...

My department itself, we had shifted from Unix workstation to few hundreds PCs... much cheaper and easier to maintain.  Although,... susceptible to  virus. . .its been say almost 10 yrs since...

Better avoid this, last year, SGTel and Pacific net were forced by court order to reveal who downloadeed it because the company who owns the right to it claim loosing royalty and not fair to those who pay for it, lodge a complain follow up with court order.  That's why, those who downloaded got fine for it.
