Windows 8 metro is a new kind of windows. Some people interested, and some don't. One point to focus on each fundamental change on OS world is the user behaviour. People may ask, how can they work without taskbar? How should they edit images without mouse? The question arise just like old days when mouse not being keyboard best friend yet.
In touchscreen era, every single software developer is working hard to create best software running on touchscreen device. Even microsoft doing the same thing, so why adobe not try? So why other software developers not try? Eventualy, they will, and every user will learn also.
The world is moving forward, and people who resist the changes surely will left behind.
