I've always been fine with being "behind" on the latest and greatest. I don't mind watching a movie, playing a game, buying a cell phone, etc, that was released a few years prior. If it was really all that great when it came out it should still be good later on.
Buying slow usually saves a.good bit of money when prices go down over time... but this time they went way up and now I'm kicking myself on it. Not upgrading the computer for now, but it is a bit overdue since I had already put it off for many years.
