Sorry, not entirely true. There seem to be a common misunderstanding about the
O/S allocation of RAM.
E.g. WinXP can only allocate 3GB RAM for the O/S, which is often enterpreted as
the whole system can only make use of 3GB RAM in total.
Actually, XP can only use 3GB RAM for the O/S, any remaining RAM is kindly allocated to applications with a max of 32/64GB for 32/64bit versions of the non-server O/S.
The rest is plain BS. XP typically uses less than 200MB, btw.
The 4GB story is coming from the first release of Vista not reporting the correct amount of installed RAM (e.g. 4GB or 8GB showed up as 3GB), which, quite understandable,
lead to a great deal of confusion among guys like us.
Both Vista32 and W732 run smoothly on +8GB RAM, same with XP.
The 64bit thing is driven by the market.

If you need 4G or more RAM then you're going to need 64 bit
