It was the style at the time! Lots of CD players had flip up tops, as did the Sega Saturn. I assume it was because the slide out tray mechanism was more expensive and also more fragile.
A friend of mine had one of those. It was super sleek to look at, but the flip top doubling as a wrist rest turned it into a CD grinder after a few years.
So I tied an onion to my belt, which was the style at the time. Now, to take the ferry cost a nickle. And in those days nickles had pictures of bumble bees on them! "Give me 5 bees for a quarter" you'd say.
