The main thing was I couldn't make the virtual screen be as good as the physical ones, and being able to see to type - I'm not at the complete touch type level - especially without reference points.
The difference is I haven't sold mine, it is still here to try some VR gaming, which I also haven't got roudn to get.
My summary is I was impressed with what the technology can do, but it's not a replacement if you have a well set up desk.
