That's because people expect non-Apple products to be much more compatible with Windows than they expect Apple products to be compatible with anything (independent of if Apple's stuff is actually compatible, which it often is). Apple is more often able to completely ignore expectations when their goal is to make something better. Everyone else makes non-Apple stuff, which 90% of the time means Windows compatible. "A non-Apple tablet where I can't run Quickbooks, Minesweeper and Notepad?! Blasphemous! I mean, this thing has an (HP|Dell|Lenovo) logo, that means Windows, so where's the fricken Start Menu?" This is why people complain that their PC running Linux doesn't run <insert random Windows software>, but few complain that their Mac running OSX doesn't. This is why Microsoft's Courier tablet concept seems so odd when you watch the video.
