Right now I am using a laptop that is 4 feet from me,which goes traveling with us, using a regular keyboard and mouse and a 28 inch screen. Due to out growing my drive storage, I have 3 external drives to use for storing information on and backing up to. I will take the smallest external with me when traveling as well as mouse. I do not have a desk in the RV, but use a large drafting 2 x 3 as a table, that I can put on my lap, or set on plastic milk crates as a table.
For internet service, all libraries have good WiFi.
