As Microsoft performance team group program manager Bill Karagounis explained that the lesser memory (RAM) usage the more battery life can save on any PC. Microsoft plans to limit memory usage in Windows 8.

Karagounis said on a blog post, "Something that might not be obvious is that minimizing memory usage on low-power platforms can prolong battery life. Huh? In any PC, RAM is constantly consuming power. If an OS uses a lot of memory, it can force device manufacturers to include more physical RAM. The more RAM you have on board, the more power it uses, the less battery life you get."

Bill Karagounis said that Windows 8 is being designed for SoC-based devices characterized by low power consumption.

He further explained that you can do the same job with less memory

He said, "As Windows executes applications and performs its own system housekeeping, program files and data are loaded off the disk into main memory. During Windows 7 and Windows 8 development to date, we’ve analyzed the pieces (pages) of memory during normal execution and how often they were referenced. The idea here is that if you’re going to pay the price for allocating a piece of memory, you’d better be using it (referencing it) often. If you’re not referencing that memory often but need it, consolidate it with something else."

What more can you expect from using this latest Windows 8 version? Aside from Windows 7 and 8 have a minimum requirement of 1 GB of RAM.
