if you use the raspberry as computer(instead of developing platform), why buy breadboard and other glitter ?

The OG raspberry, with some cheap $5 mouse/keyboard, a $10 microsd, and you have a working computer for less than $50

The OG Raspberry Pi was $50 in today's money -- for the bare board and nothing else at all.

There is nothing to discuss whilst real factors like inflation are willfully ignored.

2012 was a long time ago, and these boards were not as inexpensive as rose-tinted glasses may suggest.
