While for years people talked about planned obsolescence - the idea that companies are innovating so much they expected you to simply upgrade when the last item you purchased breaks - research suggests it's the consumer that plans her own gadget obsolescence and companies have little to do with it.
Apparently, the pace of innovation of great new gadgets and electronics is so fast that people feel compelled to upgrade relatively quickly without waiting for their gadgets to break. This creates a real issue for geeks like us, who know that some of the items we buy today will be cheaper tomorrow. What's your buying style? Do you get gadgets when they're hot, wait until price and hype cool down or go for the impulse buy?
