"While technology will never stop changing, it comes in waves, and when you’ve seen enough of them, you begin to discern patterns in the waves. Once you’ve spotted the pattern, it gets easier (or at least possible) to judge whether a new standard, format, or feature should win your bucks. Reading tech patterns is not rocket science. Consumers do it on a large scale all the time. After all, we decide which new technologies live and die. Of course, if you take the trouble to read the patterns consciously, you may be able to get a little ahead of the wave—and possibly avoid wasting some of your hard-earned cash on a nonstarter. So let’s look at a few waves of technological change and see what patterns we can find in them."Mark Fleischmann of Designtechnica has written a good article on standards and how patterns form. Figuring out how to read these patterns can help you decide what formats to invest in, but alas it will still be a risk to your data and wallet as picking a winner is usually impossible.
