Max RAM is lower with Home and Premium?

[Cluent]

I just picked up a Windows 7 book at the bookstore (can't remember the title), but it indicated that the maximum RAM that can be recognized varies by edition. I think this is where it stood:

Home Basic: 8 Gig
Premium: 16 Gig
Professional, Ultimate and Enterprise: 192 Gig

I was surprised by this, as I don't remember seeing in the version matrix that Microsoft posted. It won't be long before 16 Gig is not such a huge number. And I am glad I went for Pro, but my motivation was solely XP Mode. Another goody I had not expected to find is EFS.

Vista was the same - the x64 version dictated how much RAM you could use. However, Windows 7 increased the max quite a bit! Don't forget that starter is limited to 2GB.
