If you want to wear a necklace or - anything - you should just do it.
I know it’s hard to believe when you are still young, but when you are wearing somersetting YOU like, it will make you happy. And a happy person is attractive.
It’s just a plus that any chosen accessory will attract people who have the same taste :)
I have a beefcake laptop, that could fold into a tablet. But I still usually use it as a desktop computer: connected to all the periferials, speakers and a monitor, folded up to be a secondary monitor on the side.
While I had some cooling issues with it (had to cough up couple hundreds for repairs) I am still happy with the setup.
The phone is for during the day, some mobile only games and for reading books - tho I do like to listen to TTS when my eyes are busy.
