"Any alternate stands would have to be finely engineered for balance but I wouldn’t be surprised if some enterprising hardware manufacturer comes out with an armature in the style of the G4 iMac."
A company called Bluebroc have gone one better. They’ve designed an entire sofa around the iMac. That might be a tad extravagant but check out the armature on that thing. It looks very flexible indeed. Maybe they’ll build a sofa-free version.
