Why would it be ridiculous? If someone can use a cheap tablet for browsing, shopping, email, facetime/skype, etc, then over time I suspect that the traditional PC repair business would start declining.
Yes most of us on this forum will continue to have a PC or laptop. But people like like mum would prefer to get rid of that old ugly box in the corner. when it breaks they may be inclined to simply not replace it if the tables has replaced the functionality it offered for them.
Although not exactly an analogy look at the traditional role of a TV repair man in the 70's. I recall us having to get a guy around every few months to take the back off and solder something or replace a board. It seemed like a lucrative business looking back. But nowadays the TV is simply an appliance and when it fails we simply buy another one as they are relatively cheap.
Indeed. It's much more to do with the cost of PC's that the rise of tablets etc.
Why pay some guy to fix your PC for £250 when you could buy a new one for £200 ...
