In 1995 no one cared what a PC looked like. The driving factors were "You mean I can send a message...electronically!?", "I can chat with other people in a chatroom in real time!?", etc. But today those features are commonplace, and people really do care about how the product looks as much as the capabilities of the hardware. Does this imply some sort of plateau in the progress of the technology or the features it offers? I'd say yes - if a fully functional VR system were available tomorrow (think Oculus v10.0+) it's design would be almost irrelevant in light of the new experiences it offered.
