I was servicing Macs back then and the lC475 came with 4MB. It was one of the most expandable of the Macintosh lines and being a pizza box style, easily done by the consumer. It had just one easily reached RAM slot on the motherboard. The case was easily opened by the means of spring catches at the rear. NOTHING had to be removed to reach the memory. A reset switch on the motherboard after memory change needed to be pushed, IIRC, and the cover replaced. WHY would you, with your experience, need to have any help at all to exchange a single 72 pin SIMM????
Sorry, but you were NOT talking to an Apple employee, since at that time, did Apple have any Apple stores for you to meet one. You would have been at a 3rd party store that was merely an "authorized" dealer and repair station. Apple did not open it's first Apple Store until May of 2001. At that time, many of those "dealers," especially the big box stores and office dealers, looked down their collective noses at Apple users and were not averse to letting the users know it. You were right in the middle of that time. . . and it was the PRIME reason that Steve Jobs made the decision that Apple had to open their own stores. . . to get around that problem. Now according to JD Powers, Apple has had the best customer satisfaction record in the world.
I left that machine, along with my ex, a long time ago, and have no need, nor desire, to get into a spitting contest about how wonderful and great Apple computers are, and have been, with anybody.
Have a good day.
