10 years full time doing break/fix as a one man operation out of my house and I am still seeing steady work. I am in a major US metro area, located on the right side of town, have well over 2,000 customers, and I get quite a bit of repeat business. I mainly support small businesses (less than 10 employees) and high end residential customers. I have quite a bit of drop-off/pick up traffic at my home and that has not appeared to hurt my business.
The fear I have (regarding the decline of our business) is that the smart phone and tablet could eventually replace the PC. I started a thread about 3 years ago on this topic. Since then PC sales (and profits) have steadily declined, Intel has made a major shift to focusing on the mobile market, and all the other mobile software and hardware manufacturers are growing. PC market declining - mobile market growing. That speaks very loudly about the future.
The only thing (in my mind) that is preventing this "market take-over" from being reality is a little more CPU power, a full-sized keyboard, full-sized mouse, and a full-sized LCD display. I think there will be a day that you will walk into your home, set down your phone on your desk and your 24" monitor, mouse & keyboard will recognize it and will work just like a PC. My phone already has 14 Mbps/4 Mbps (down/up) broadband in my house so my home already doesn't need a cable broadband Internet feed - who'd a thunk that 7 years ago?
I honestly believe we are not far from all that happening. It will certainly take a more robust Android-type OS to handle it - and I assure you Google is not sitting around twiddling thumbs right now. Nor are the cell tower providers, cell tower equipment makers, and cell phone hardware/software innovators. They are all constantly on the move growing and innovating their products in this direction and their stock prices reflect that. We are only 6 years and change since the release of the iPhone and look where we are today with the smart phone. It's pretty darn incredible that they have made such a huge dent in the PC market. I think that trend will continue to play out but I do not yet fully understand how that will impact me personally.
