My wishlist for a smartphone

This is my wish-list for a smartphone. I believe that a 'smartphone' must have these features, else it cannot be called a 'smartphone'.

1. Lesser Memory Footprint.

Android 4 needs 512 MB to just run. If you want to install and run additional applications (like 3D games or even Temple Run, for that matter) smoothly you need 1GB RAM. Preferably a dual core CPU. With that configuration on my 5 yr old desktop, I run Windows 7 without any issues.

2. Ability to Switch Users

There should a provision to switch users from the lock screen. This would simplify everything. I can give my mobile to anyone without worrying about kids make an online purchase unknowingly or adults snooping knowingly. Do you understand privacy?

3. Ability to Remove Unwanted Software

I do not use Facebook. And I do not want a 20MB application on my device which I have no use of. Unfortunately, I cannot remove the application completely. I can only uninstall the updates. Not good. 

There are some more coming. These are the ones on top of my head right now. 

And I still do not see a use case for a high end mobile phone (4/8 core CPU, 2GB RAM, dedicated graphics). When and where will all the 4 cores be used, even to 50% of their capacity? If they cannot be used (for the want of battery performance or excessive heat or any other reason), why have so many cores? I really do not know. If anyone knows, please reply back.
