I do find it quite frustrating that MS are forced to Rebrand their UI again. However I would happily berate Microsoft for yet another pointless name changing exercise of their software but this time they have outside parties saying they cannot use the term "Metro UI"

Bit of a bugger for MS IMO, this time they are actually trying to unify their branding and now they have to contend with this..
