Detail about the cha cha

Hi, currently i own a Motorola Milestone but i am considering a new phone. I was just wondering a couple of things:

- Does the size of the screen affect using the phone that much? like navigating menus.
- How supported by apps is it with a unusual screen size?
- Does anyone actually use the Facebook button or once you get it is it like any other android phone using Facebook?
- How long is battery life?
- As for games, i don't play much but does it support many? e.g angry birds or gameboid?
- Is it true about flash not working on it?

Are there any problems with the phone?

Thanks
