I can't see how there will ever be money repairing smartphones or tablets. They are disposable.
I think that setting up networks, configuring backups, server administration and educating users, may be the best bet for the near future. There are still many business in the Tampa area that run there own exchange servers, file and app servers.
Tell that to the guy who just spent $500 on a tablet, that its no worth repairing. We'll be fixing them, but I'm guessing the prices will drop like a rock, then no.
