Yeah, I know what you're saying. (But we're getting off topic.)
Let's not forget that with Win8 Pro you don't lose anything you already have with Win7/Desktop (except maybe the Start orb, and a boot straight into Desktop, soon restored for those who want an older UI). All the Win32 apps you traditionally use still run just fine. So keep on using Photoshop as you always have - it would be silly to move to the Touch version, which is not touted by anyone as a replacement for the full Win32 version, btw.
Touch devices are for now and the foreseeable future really aimed at info consumption rather than production and manipulation. MSFT has to make a start somewhere, because devices are a big part of anyone's future.
As the migration of iPads and 'droid fondleslabs into the office/work environment shows, not everyone needs only a laptop/desktop all the time ... there's room for both, and millions of people can benefit from having both a notebook/desktop PC and a fondleslab.
Win8 Pro supports various platforms ... notebooks and laptops for Win32/Desktop users who want portability, desktop PCs for those who work at a fixed workstation, and tablets in various configurations for those who want a bit of both.
It's really not such a "mess" at all. Nor is it a big disruption, chaos, confusion, or disaster, in my view. In fact, it's all coming together rather nicely.
