Jeff, I do hope things will improve, but I won’t be convinced that 64-bit has hit mainstream until I see major OEMs shipping PCs with Vista 64 installed as standard.
Personally I wish Microsoft had only released a 64-bit version. After all, it is supposed to be the OS for the next generation of PCs isn’t it? And I doubt many of them will be 32-bit.
