"Peak of feeling fancy when you have something new and special."?

"Peak of new people having access to their first cdrom drive"... hmm.

"Peak of this new thing totally changing the game, even if it gets more popular later, because it's mundane by the time that happens."?

"Peak of breathless press releases about MuLtImEdIa Cd-RoM"... That's probably it.

Peak of hype/excitement - many things have their technical peak (most units sold/most units in the field) after the real "popularity peak".

CD-ROM drives first started not being put in Mac laptops in 2008, so the peak "units sold" would have been somewhere in the early 2000s. But by then Internet speeds were fast enough and other methods existed, so they were waning in popularity/excitement.
