Been PC user since 1990 and am at this time totally sick and tired of having to deal with MS OS. Using Win 10 on my Dell. Interminable downloads and multi boot issues. Have had enough! Looking a Chromebook. I am not a high end gamer user. Just research, email, word docs, spreadsheets and the like. So here's the question, a recommendation with a budget around under $450.00. A reliable unit with at least a 13" screen. Would appreciate any comments. Thank you.
