How hard is it for Microsoft to provide a framework so that people can add their own custom skins to the Metro UI ( I know the Metro name is dead...but stick with me ..OK ?) .
Honestly, the current bland looking backgrounds and flat tiles are really *UN COOL*. And I think this is what may be discouraging lot of yuppies from adopting Windows phones and will discourage from adopting windows surface tablets.
Just my 2 cents....but Microsoft will need their mental abilities to be checked to ignore this simple enhancement.
