A user session to Oracle takes much less space under NT than for UNIX simply because of the thread vs process architecture. Lets assume a session on NT takes about 2M (since threading allows for shared memory segments). The same sessions for UNIX would be ~ 10 M each (because they are independent processes) so NT reaches its 2G limit with 1024 connections. Assuming 10,000 connections (Your minimum claim for UNIX) - UNIX will need 97G of memory. I would rather have 12 2G NT boxes that are in a cluster - fault tolerant, faster and 10s of thousands of $ cheaper that the UNIX box that does the same job.
