Thanks for all responses.
PinkElephant, in regarding to this: EN with full features (if you need them all or not) costs less than a cup of Starbucks brew per month
(1) why should I pay for features I don't need?
(2) These days, people have to have lots of subscriptions, to name a few: amazon prime, amazon music, YouTube red, cloud storage, office365, Netflix, Nest webcam subscription, ....
Although each cost not very much, but they can add up to a good amount of money which you can not make it by saving a cup of starbucks brew per month.
