The "live" part of the name is there to imply IT'S ALIVE!
- It moves
- It changes
- It updates (all by itself - seemingly)
This is where the added value is.
If it just sits there and doesn't do anything it's probably just an icon.
Having icons may not be a bad thing. Just know the difference and that live tiles are like icons on steroids (but without the negative connotations). :)
