That's not my point
I do use WinRAR a coupe of times a day, and I'm happy it's faster in those situations. but my other applications Firefox (64-bit is a crime) Photoshop (slower when you're not memory limited) and general office applications either just don't show any improvement or tend to be limited by them being 32-bit in a 64-bit environment.
I want 32-bit to die yesterday but there are enough apps/games that simply don't benefit from a 64-bit environment and because of that offer no benefits for users to switch from "ye olde" to something a bit more commonplace in todays CPU architecture.
The point is that there are plenty that do benfit from 64bit os's and there are more every day and every day there are less that don't.
