Metro always looked useless to me as a desktop UI.
The advert showing on TV at the moment sums it up, lots of swiping and arm waving in an exciting 'Minority Report'/'CSI' style and some guff about space and birds. The result of all this faffing about?
A high score in a Star Wars themed version of Angry Birds.
The entire advert sells the product as something you can do on your phone with a flick of your finger, instead of more arm waving than Magnus Pyke* at a rave. Let's face it, unsexy office type stuff is what Windows should do best, pretty much everything else they try is dad dancingly embarrassing. Haven't tried a Windows phone, but I'll take your word for it that they're good. Holly Willoughby likes hers at any rate.
*one for our younger readers.
