Here's an article that change came discussing why people are leaving Apple and for Windows. It's very compelling.

Very good read! I'd could write it myself if my english wasn't that bad. Also the comments gives a good read.
Just saw a writing on Appleinsider where they try to explain there isn't future in the mac anymore because of declining sales. When looking at the graph I see even more decline in iPad sales but still talking it's the future.
My point is: you can make or break the future with a product! Hardware and software needs investments to evolve. If you don't do neither it's lame to tell everyone the future is different. Microsoft understood but the hardware wasn't ready. Apple just stood (as good as) still for at last 4 years.
