Also companies and organisations would have to retrain Dorris the 65 year old receptionist to integrate windows8 into the office.
Actually I do not think that is true. You have someone who is not that great with computers and they have to click start, programs, office, excel so that is 4 mouse clicks if they get it right.
Windows 8, login click the pretty Excel icon job done, I do not think much retraining is required from a company point of view, what I would like though is a method from MS so as a company we can deploy the Modern UI with a pre-laid out style with the Apps we want on there, and considering most people use IE and Office then it is ideal.
