You both have a point. Clearly not a lot of individual applications really need more than 4GB (though unfortunately, many are pushing up for the wrong reasons), but then a whole category of them would greatly benefit of expanded RAM availability.
I would phrase it as the greatly expanded address space. This offers a ton of benefits even if your app uses very little actual memory. For example, the stack size problem for threads pretty much goes away. Garbage collection can get much better. You can have much better hardware detection of wild pointers.
