Microsoft to Launch 64-bit Windows on Monday

maotx writes "Several news outlets are reporting that Microsoft will officially roll out 64-bit versions of its Windows operating systems on Monday. As compared with existing 32-bit versions: 64-bit Windows will handle 16 terabytes of virtual memory, as compared to 4 GB for 32-bit Windows. System cache size jumps from 1 GB to 1 TB, and paging-file size increases from 16 TB to 512 TB."

Are there any 32-bit-only OSes left worth mention?

Just wondering. Obviously Solaris, IRIX, Linux, AIX, Mac OS X and whatever other UNIX flavors are out there (well, except for maybe SCO...) have had 64-bit support for some number of years now.

Is Windows the last major commercial OS to add 64-bit support, or are there others I'm missing?

(Even if it is the last one, I'm sure Microsoft will tout this as supremely innovative. :)
