Speaking of not displaying our tech things in public...
My friend just bought a MacBook and he wants to install a word processing program so he can use it for university. He's asking me to skip class tomorrow to meet with him and help him install it (because he needs it the day after tomorrow). He would be
embarrassed to actually bring the computer to class* and do it there, because nobody carries their laptop to class around here. We use old-school notebooks.
I did a semester in Madrid and I took my laptop to class there
instead of a notebook. Everybody did. It was normal. Here... it's seen as sort of pretentious.
*I mean it, embarrassed, even though it's new and he adores it and he spent a year gathering the money to buy it so he's pretty proud of it now.
