I bought mine used. I have the celeron proc. type. WTH 4gb  It worked perfectly from the start. I added a touch screen ($150), and I added 8gb ram (which I found).  Perfectly smooth and responsive for the school work my 1st grader does.  I used it for zoon and Skype also (added a web can of course). Google docs, and web browsing. It is easier to use and works as well as my i9 64gb pc. I do not like the power button. Hard to tell if you have pressed it.  The price has gone up.  My used unit was less than $200.  I'm happy with the price I paid.
