Microsoft has 64 bit versions for a lot of their products. But 64 usage has not gone mainstream. I understand why the are not going beyonnd the 2gb, but it's hard to understand why they are not supporting 4gb.
Yet Another Guess (YAG), it's a hardcoded limit in the OS. XP will support 4GB, provided the boot.ini file has the /3gb switch for the kernel. Even if you put 4GB in a machine, without that switch, it'll only see 2GB max. Even with the switch, XP still does odd things, and no single application will have access to more than 2GB. So, with that hard limit in place, there's no reason for a laptop manufacturer to go to all the expense of supporting more than 4GB at the present time.
