Welcome to Unix HQ - your Unix Headquarters for SUN, HP, IBM, and SGI systems!
UNIX systems have mostly catered to enterprise use where the demands placed on them are stronger. Whereas a typical PC is designed to fail after 3 or 4 years with moderate use, enterprise UNIX systems are built tougher, typically lasting 25 years and thus carry a justifiable price premium over their PC counterparts. Because the Internet by and large has always run on UNIX, there will be continued strong demand for UNIX systems and expertise. Knowing UNIX means you will have an advantage in the increasingly competitive I.T. job market.
