Including lying that Microsoft promised desktop Apps would work on Suface RT.
The problem Microsoft made for themselves with WindowsRT is that that made no platform distinction between "RT" and "Pro". It's not anecdotal, I actually know people who went to PC World, had a tablet demonstrated to them, they were told "it runs windows, so you already know what to do"... They get it home and it doesn't run any of the software they already have despite the fact it is running windows... Oh and none of that cool software iPad owners are running works on it either.
The problem when selling a consumer device (which a Tablet is), is that the consumer doesn't care about the platform, if it looks like windows it should run the stuff they have for windows. Apple were very carefull to ensure people don't confuse their tablet and desktop platforms.
