I actually liked the idea of Windows 8 tablet with laptop like power. However due to battery life, cost and reading of hardware reliability issues with different Windows 8 tablets I wasn't confident in buying one. I was doing work one weekend at my parents house on my laptop and some of it I was doing via RDP connected to my desktop at home. I for some reason decided to test RDP access with my girlfriend's iPad and found the picture to be better and the responsiveness of the tablet superior to my aging laptop. In the end I ended up buying an iPad and a bluetooth keyboard case and it is working well for what I wanted a Windows 8 tablet for.
Admittedly such solutions don't work as well for non-technical people, but a lot of them don't need the heavy lifting of a desktop and could make due with a keyboard case and Google Apps or other alternatives if they really were frustrated. All this combined with the fact Windows 8 just doesn't make sense without a touch screen is why Microsoft's been having trouble selling Windows 8.
