Understanding Virtual Memory on Windows Mobile

I have heard a lot of complaints on the virtual memory on Windows Mobile.
Today I happened to read an article from Micrsoft.
The article is about change list and migration guide from WM 6.1 to WM 6.5.
As a usual application programmer, I don't care about the behind scene of system memory management. But my colleagues (especaially camera application developer and system developer) always have been complaining about the shortage in virtual memory.

So I took a chance, googled and found good articles on the topic.

Here is the permalink.
