In thumbing though many Craigslist ads, I've stumbled upon a couple of ads for iMac G5s that need a little bit of TLC to get going again. While contemplating ideas on whether to purchase or not, I hit upon an idea. At my workplace, we have wi-fi inside the building that I have access to. If I were to pick up one of these iMacs and use it as a mobile device in place of a laptop, what kind of pluses or minuses do would one see? Aside from the weight and size factor,s which I would have to find some kind of case, or build some kind of container for, would the iMac be suitable for this kind of mobile use? I'd be bringing it into the office up to four days a week for several hours at a time. Ideas? Thoughts? This would be an inexpensive option ($50 or so) to PowerBooks or older MacBooks that I have trouble finding at the right price. I've taken a couple of iMac G5s apart back in 2013 and that is the outer edge of my mechanical prowess, so upgrades are possible, but things get a little dicey after that if strong repairs are needed.
