Had a wide ranging chat around this with some friends, and we pretty much came to the conclusion that monitors are dead, but only in the long run. The tech for crystal clear screen definition is already well on the way, CV1 is going to be a big leap and theyre
developing 4k screens for smartphones so its only a matter of time really.
Input is another issue altogether, but hardly insurmountable. Keyboards we reckoned wont be replicated but another VR specific input device will come to the fore, voice most likely. Elite has Voiceattack as an example, you can pretty much dictate anything now with dragon etc, and input devices like haptic gloves can push or pull creativity software for presentations or design anyway you want to. Its just going to be a different way of working.
Of course, there will always be the Windows XP users, or businesses that take ages to move on. But hopefully, without some major derailer (VR makes you go blind in six months!), this is the future.
