a couple of people I talked to said there isnt any money to be made in it,that most people will replace a pc before getting repaired. This is beacuse a repair may cost £100+ and as you can pick up a pc or laptop brand new for £300 then whats the point in repairing an old one. I am studying for the Comptia A+ exam but also been told thats not important as its just a certificate! I live in UK so answers about US market may not be useful to me
