Earlier quoted context omitted.
You're counting N and KN versions, 32+64 bit, checked/debug? Or what exactly? I'm sure Apple has SKUs for other countries, where they need different power adapters. The core Windows licensing is down to 4 now, right? 2 on desktop, 2 on server. SQL Server on the other hand...
Why is there even a distinction between 32 and 64 bit versions? Why does a customer have to know anything about it? Maybe just to f * customers which: a) bought the wrong one and now have to buy another one, because conveniently, they can't just return it. (at least in Europe that's the case) b) want to upgrade their hardware at some point in the future from 32 to 64 bit, without having to buy the exact same software…
these distinctions are not for consumers, they're for IT managers when they're rolling out across a large number of machines, not all of which may be 64-bit compatible.
