For an old tech challenged man like me, would I be better off buying the DVD version for $5.95?
If you are “challenged” enough that you are nervous about burning a DVD, That is certainly one of your options. If I were you, though, I’d find a friend that can do it for you, and save the money.
If you are tech challenged, don’t do it.
Linux is great but if you are challenged, get someone to set it up for you. It’s not hard to do, it’s just different.
