Once I've got used to the metro GUI I really like it.
This is from an OLDER Guy who absolutely HATES doing anything with mobile phones apart from using them to actually make telephone calls, jam incessant noisy business guys on Eurostar trains between London and Brussels/Paris especially on Fri evenings and receive the odd text.
===> I've only ever sent TWO texts in my life and it was such a horrible experience that I will probably never send another one.
IMO MS has got this OK
-- It beats the Android system hands down -- having seen how apps work I could even use them on a mobile phone --but as you get older rules of A.D (Anno Domini) take over - you can't see the small text and even attempting to type on those tiny keyboards where your fingers are the size of Steam Shovels or JCB diggers compared with the tiny square you have to touch is a big no no.
