I loved this quote recently unearthed in one of the many Microsoft legal disputes. This comes from an email from a M.$. employee to Bill Gates himself...

"the Windows API is so broad, so deep and so functional that most ISVs would be crazy not to use it. And it is so deeply embedded in the source code of many Windows apps that there is a huge switching cost to using a different operating system, instead. It is this switching cost that has given the customers the patience to stick with Windows through all our mistakes, our buggy drivers, our high total cost of ownership, our lack of a sexy vision, at times, and many other difficulties. Customers constantly evaluate other desktop platforms but it would be so much work to move over that they hope we just improve Windows rather than force them to move... In short, without this exclusive franchise called the Windows API, we would have been dead a long time ago."

If you could go back in time and re-live any experience you've had, what would it be? I'm not saying you could re-do an experience, but just go back and experience something again. So, it won't change the future, you just get to go back and feel something and experience something again.
