So you can't count. And this post proves it.
Starter if you want a netbook (they do sell those here in the US, correct?)
Home Premium x86
Home Premium x64
Professional x86
Professional x64
Ultimate x86
Ultimate x64.
I still count 7. Way too many.
BTW - save the pejoratives for someone who values your opinion.
Wait, what... You're imagining things? I had a feeling you were crazy.
In my first reply to your post, I said "Pretty much you have two choices now." Which is something I still stand behind.
Either Home Premium or Professional. Ultimate has no real benefit over Professional, unless you're looking for Server functionality... and then you should look into Windows Server 2008 R2. (There's Snow Leopard Server too, in case you didn't know.)
Starter is only sold to OEMs. You can't upgrade to it. I said it "might be for netbooks" not that it would ever make it to market here. I mean, Microsoft (and consumers) would probably rather see Home Premium on Netbooks.
Your whole x64 and x86 thing is crap, since every retail box includes both. Check Amazon from now on before you spout your misinformation.
Also, the REASON behind providing both x86 and x64 is a logical one. Compatibility. It's a problem several of my apps had when I switched to Snow Leopard. Sure, most ran fine in 32-bit mode... but a lot still haven't been updated with 64-bit support. Windows is all about legacy compatibility (which is what adds to the bloat and most of its flaws). I've run 64-bit Windows since Vista... and I've never had any issue. At least Microsoft GAVE users the choice. Rather than forcing them to stick with 32-bit, and then forcing them to pay for a 64-bit version in the next release. (Like Apple did.)
Microsoft's offered 64-bit since XP. Hence why Vista's 64-bit was decent, and why Windows 7's 64-bit shouldn't give anyone any major issues.
The 64-bit version of Vista and Windows 7 will load 32-bit applications, no problem. The real issue with 64-bit Windows XP was lack of drivers.
Clearly, that cuts your choices back down to:
Home Premium
Professional
Ultimate (which, as I've said... if you want those extra features, look into Windows 2008 Server R2)
And thus, for consumers (who probably don't give a damn about servers), you get:
Home Premium
Professional
