No I would expect people to do whatever they want with their money. Frankly, I am sure we all know someone or several peope who do buy the latest and greatest. Obviously, vendors like this and keep them on record to send advertisement and other "bait on the fishhook" for these kind of customer.
Many people do buy whole new stereo systems as well as individual components. I wish I could see a statistic on this but I would not be amazed if the majority of consumers did buy new toys every couple of years. My boss just threw away his VCR and picked up another after only 2 years. I still have one from 97 without any problems and the last thing I am going to do is purchase another one, but thats just me.
