I feel I'm in the same boat as you (home/work Windows user, tablet owner), but I do feel there is a need to go this direction:
- There are some dedicated apps for tablets I often wish I had on my laptop. It wouldn't be hard to get these apps on Windows, there is just a lack of a built-in app store model to make it easy. Plus making app install/uninstall easier on a computer is a good thing (not sure if this will be the case).
- When using my tablet at home I often finding myself wishing I had a keyboard, and I almost always end up reaching for our 13" laptop to get stuff done.
The way the media portrays these things, you'd think there isn't any room for a device that has the best of both laptop and tablet worlds, but I'm a believer. Maybe not with this version though, maybe Win8 SP1 or Win9?
