As a long time Linux user, this quote from MSDN nearly spilled my coffee (emphasis mine):
Fundamentals such as memory usage represent a key engineering tenet of Windows 8. In building Windows 8 we set out to significantly reduce the overall runtime memory requirements of the core system. This is always good for everyone and especially in a world where people want to run more and more apps at the same time or run on systems with only 1 or 2GB of memory.
I'm happy to read this post and see engineering has a seat at the table for Windows 8. Funny world where memory is next to free.
