Not long ago I wrote a blog about the new Mac Mini just announced. The improvements Apple made were encouraging that the Mini would now be an even better mainstream option for computer users. But I had no plans to get one myself when I wrote that blog. But a bit of bad luck changed the situation. My relatively old office Mac Mini was knocked out of business by a “mini” external hard drive, one of several brands designed for convenience with the same lateral dimensions as a Mini and intended to sit under a Mac Mini. For some reason my little “mini” external hard drive failed and got very hot, and that damaged the Mac Mini sitting above. That was the second time I had one of these “mini” external hard drives involved in a problem with a Mac Mini. So a lesson finally learned. Convenience sometimes has a price. Oh! well, the new Mac Mini is a larger shape, so those old “mini” external hard drives are a thing of the past, and that will be a matter of deliberate choice in my case.
