Hi Mem, I think we all know that you are very open to change. However, the reception of Windows 8 should tell you that most of the population is not. Is it an "old" style? Yes. Does it work? Yes.
I'll give you an example: I do IT work for the retail industry. One of these retailers just went through a major system upgrade: registers, controllers, servers, staff computers, everything. When upgrading the Fujitsu uscan system, the entire application had to be re-written, but in the end, the gui looks exactly the same as it did before, even the voice is exactly the same one that was used since the system was released 20 years ago. The latest system offers more functionality than the older systems for sure, but many customers wouldn't even notice.
Why? most people don't like change, and Windows 8 is just another example of this fact.
