But Apple says that Lion needs only 2GBs to work! What's going on here?
It is true that Lion will work in 2GBs. It is not necessarily true that the experience will be enjoyable, unless you run apps which have low RAM demand and run few of them. For example, if you just wanted to run TextEdit alone on a 2GB Mac, you'd probably get great performance under Lion. It's marketing-speak. If you ask me, I'd say that 8GBs is the smallest realistic RAM size for Lion if you prefer a hassle-free experience, and if you can get more, do it.
Why is Lion using up more RAM, this sounds like it is less efficient than Snow Leopard, isn't it?
New releases of operating systems always use more RAM. Why? To save I/Os, to save you time, and to fit new function into your system. Because RAM is cheap and getting cheaper all the time, OS designers are always looking for ways to use more RAM if it will provide a benefit to the end user. What they are doing is optimizing expensive resources, like your CPU, and HDD accesses. And your time! RAM is not an exensive resource.

Revert to Snow Leopard, many have, it's just not right for pre 2011 hardware in my opinion.
