We have seen absolutely nothing in 8 from last year, or 8 from last week, that is a compelling reason to burden our clients with it's inherent learning curve. The vast majority (>90%) of desktops which we support are used for LOB software which in most cases (again >90%) is loaded after login and remains running until the end of the business day. Our clients cannot be the only ones that use business desktops in this manner and so far, nothing about 8 enhances, or even deals with, that fact.
