I know every computer box needs a CD/DVD reader in order to boot the thing up under adverse conditions (and your system should always be set up so that you can do this, by the way!). But as a matter of actual functionality, maintaining a current and high-functioning version of this sort of device, or two or more of them especially, built into the box is usually a bad idea for me. My computer boxes are not ever conveniently located. For my main computer, I can reach the off on switch with my toe, which is how I start up the machine. (The button is not needed to turn it off, of course.) So I can’t really easily reach the CD/DVD drives. And, over time, these drives get old, or slow, or just don’t do everything you want, and if you have two or three computers in the household (don’t forget to count everyone’s laptop) an external DVD/CD burner/reader might be a better option than trying to keep each machine functioning in top form.
