Re: Obsolete within 10 years?
Looking at the rate at which new versions of Bluetooth and new wireless protocols are introduced, that sounds about right. Then there's battery life - two years ago 50 hours was considered very good for a mobile phone, now the best ones run 4 days.
Mechanical watches have been good enough for all normal purposes for perhaps 70 years. That possibly explains why some of them can be so expensive. But a product that is likely to underperform by a factor of 2 on at least one significant feature in a couple of years is surely not going to be in widespread use in 10 years time.
