I'm sorry, but the Cube is the single most important and consequential machine Apple ever made. Its design cues pervade everything from their flagship store to the individual keys on the keyboard on which I'm typing this. Nearly everything they've sold in decade-plus since bears the stamp of that glorious and utterly unprecedented machine. It's the entire Jobs/Ive aesthetic and philosophy in one box, a prototype for an entire company - one which has since grown into the most valuable one on the planet - and they SHIPPED it.
@philwelch is right. It's a work of bloody art. It's in MoMA's permanent design collection for a reason. It's the Neil Armstrong of personal computing. If it's a mistake then so was Newton's Principia, the Declaration of Independence, and Sgt. Pepper's Lonely Hearts Club Band. Seriously, it's that good.
If you're going to slag on something, slag on the hockey puck mouse. THAT really was a POS.
Sorry but I'm not buying that. I can see that squares with rounded corners are everywhere in apple's design. I don't think that comes from the Cube. It was just a result of this love for the rounded corner square.
Take a slice of that rubbish bin's midsection, and you have the Mac Mini. Tilt that Mac Mini on its side, perforate either end, then add some handles, and you've got the G5.
You can play this game with just about everything Apple has sold since this machine was introduced. Virtually all of it has some design cue that can be traced back to the Cube, and no further. It really was the Genesis Box.
Ive's work in plastics hasn't held up as well since the switch to metal and glass, but at the time it was a remarkable, groundbreaking example of industrial design. The next year, of course, they launched the titanium PowerBook that spearheaded that transition, though it would take about a decade for plastics to be phased out entirely.
