just an interesting, personal point…
When i was in high school I didn’t have a cell phone, but when i moved on to further schooling which was further away from school, I got one.
Although it was very convenient to have one, as mi keamcha yisroel said exactly:
I really notices that it took away from my learning.
At first, I would never bring it to class, but as time wore on, and the first time i had to go somewhere directly from school, I started bringing it to class on silent…
and so on…
and boy was it so distracting!
not that a cell phone is a electronic gadget… well, on the other hand…
