Yeah, if your ‘work’ consists of playing angry birds.
Win 7 is an excellent platforum and OS.
Don't knock what you don't know. Tablet-based work is still work.
In fact, IT can limit the tablet to just doing work-based tasks, and by keeping storage of documents on the net, you make your data more robust and available for sharing. Always-available 4G networks on tablets mean that you're never out of touch with that collaborative data, or remote-wipe a device if security needs require it.
Can the same thing be done on Windows? Sure, it can with any OS. But tablets are cheaper, more portable, and have everything for this style of IT built right in.
Win 7 is an excellent platforum and OS.
For what it is, sure - I run it, along with Mac OS, and Linux. There's nothing really wrong with Win 7 at all, as far as being a modern "heavyweight" OS. (Putting aside my UNIX biases for the moment.)
But heavyweight OSes are overkill for many business tasks. Running a pay point? (Used to be called a "cash register"?) Writing sales pitches? Filing an expense report? Communicating via e-mail or IM?
If the task could be done 12 years ago with an XP computer, odds are that the task can be done today with a tablet. To many businesses and workers, that's of great appeal. CHOMP! There goes PC sales down the toilet.
