I'm thinking about freelancing in computer repair until I find better work elsewhere. What kind of hardware do I need? I'm thinking about buying a refurbished Macbook (the cheapest model I can find), some screwdrivers, as well as an upgrade to my Treo 700p's data plan to unlimited so that my Macbook can get online via the Treo's EVDO. Of course, a problem is that the upfront investment will hurt the pocketbook a lot. And I already have a lovely iMac G5 Rev. A, so a new laptop solely for fixing computers might be overkill. I don't think using the Treo *as the laptop* makes sense, either. Any suggestions?
