I am the perfect target of Windows 8. I use a touchscreen laptop (Lenovo x220t) and I love it--I work with the pen as much as possible, even when typing would be more efficient, simply because I like it.
I and users like me have been complaining since Windows 8 released that it's simply not a good touch/pen interface. Windows 7 had an excellent pen input system. Microsoft scrapped it and replaced it with a much less useful and less practical input interface in Windows 8. It was a bafflingly stupid decision--they dumped the best interface in the industry for something that's barely functional.
Reviewers haven't paid much attention to this problem because, I think, relatively few people are using the pen as a significant input device. But Microsoft is trying to change that. If they want Windows 8 to succeed, or PCs to move towards a touch/pen interface generally, they need to ask some hard questions of whoever is currently in charge of those design decisions. (I'd recommend, "Can you name any single way in which the Windows 8 pen interface is superior to the Windows 7 interface?", "Then why did you change it?", and "Have you been drinking on the job?")
