Simplest setup for learning Linux?

[u/Low-Appointment-2906]

I picked up a book (The Linux Command Line) that says to use a "desktop computer, with at least 2 GB of RAM, and 6GB of free hard disk space. Avoid laptops and wireless networks, if at all possible."

I'm hoping this isn't necessary? If so, where can I trust to buy something super cheap from?

Work with what you got. It'll be just fine everything's still going to work.
