64-bit CPUs have been around for about 10 years now, maybe more. Most computers have such CPUs (I don't think 32-bit CPUs are even manufactured anymore).
And there are a lot of computers that have more than 4GB of RAM (especially in the consumer sector), which 32-bit OS-es can't work with (let's ignore PAE for the sake of conversation).
In these conditions, why is there a 32-bit version of Windows 8 ? All editions (regular, Pro, Enterprise and RT) have a 32-bit and a 64-bit version. Aside from the RT edition, having a 32-bit version just doesn't make sense to me.
Shouldn't we completely give up on 32-bit OSes ? Is it still too early ?
