I can't find any data on MSRP now, but back in the day it seems to me that there were storage choices that were not so cost-prohibitive for consumers.
Not so cost-prohibitive? "Back in the day", I remember a particular consumer 20MB (not a typo) HDD went for about $1500. A tape backup system was similarly priced (from memory).
I shudder to think what an educational institution paid for the massive *5MB* networked drive hooked up to the old Apple IIs. Ya know, back in the day.
Now get off of my lawn!
