Resistance to change

Recently i have upgraded my laptop software to office 2007. It is kind of new thing to me, cos i felt like i need to re- learn office. The layout is totally different and that is what called "ribbon setting" haha.... i see the reason why the design is being 'improved' to become ribbons --> less clicking --> more efficient. But i still see people resist to change. Some of my friends don't even bother to take a look at it just because of the new face lift is too 'shiny' on them and difficult for the to adapt, etc. Anyhow, i see this as normal. When it comes to things that totally change the usual perception, 1st reaction is always back off first -> wait and see. But i think MS is pretty smart about this. And could be the reason why they changed the format to .xlsx to signify the version. In fact this will eventually impact everybody who use MS office ; as more and more people is using the offie 2007, it creates the demand to change because the file will no longer be compatible to other version. Currently for compatibility reason, i always save my files to 2003 version, however when more and more people start using 2007 version, saving the file to 2003 becomes inefficient in work place and the people start to shift for upgrading to office 2007 .... MS really have a smart move to shift people towards efficiency by less clicking yet forcing people to change another way round!
