Microsoft has pulled back the curtain and given the world its first glimpse of what we can expect from Windows 8. Microsoft made a point of clarifying that Windows 8 will run on existing hardware, but it failed to mention that you might need a new desk.
I should know. I already have a touchscreen monitor that I connect my laptop to when I am sitting at my desk. It is an Acer T230H 23-inch monitor. I thought that it would be really cool to be able to interact with Windows 7 via touch, but the reality is that is highly impractical. I tried it for a while, but my shoulders get tired pretty quick when holding my arm out straight in front of me for extended periods to tap and swipe the screen.
What Windows 8 needs is a desk where the monitor lays down instead of standing up on top of the desk. But, a completely flat monitor would also be a pain ergonomically–both in terms of the viewing angle and strain on your neck, and in terms of having to reach out across it to tap and swipe.
But, if the monitor were lying at a slight angle–with the base essentially making contact with the top of the keyboard, it would be in a good position for viewing, and in a reasonable position for working with the touchscreen interface.
So, Windows 8 will work on my existing laptop hardware, and Windows 8 will work with my existing touchscreen monitor. But, I need some new furniture that make it practical to actually use the touchscreen monitor. Microsoft needs to coordinate efforts with furniture makers like Bush, Sauder, and IKEA to develop new desk designs that position the monitor for Windows 8.
