Typically, I prefer a printed manual because I find it easier to âjumpâ from pages in different sections when I am trying to find specific information. However, I do keep digital copies of said manuals on an electronic device for portability. I find that if the document I have is in PDF format a screen smaller than 10â makes it hard to read without zooming in and therefor needing to scroll back and forth to read the text. Thatâs the disadvantage of old eyes I guess. The device youâve linked to is probably a bit overkill if you are just looking to use it to read manuals that you would like to have at your disposal. Personally, for me, I like to use the Kindle Scribe for accessing my PDF manuals. Granted, the device is a bit larger (10â) and only black and white however the Scribe gives me the advantage of having my manuals available as well as an electronic notebook where I can take notes, sketch my designs, etc. Making an assumption that the manuals you are wishing to have at your disposal are in PDF format you have a number of options. You could use your smart phone, an ipad or a number of other devices capable reading the format you are looking to utilize (ie. PDF, epub, .docx) etc.
With the tablet option you have many choices. You can get a used tablet relatively inexpensive or even recycle a device you may have laying around the house. In the end, your eyes will be thanking you after a day of reading and making chips!
Youâre on the right track, you can pickup the latest model of Kindle fire 10" tablet for about $180, I imagine you might be able to find a âused like newâ or previous generation for even less.
As @edmcgov suggest I use an old iPad that wasnât up to snuff for modern browsing and gaming anymore (I think it was my sons, itâs probably six or seven years old) BUT, just for displaying a PDF file itâs perfect and if I have an accident in the shop with it, Iâm not crying in my soup.
