Here's the surface, a line of devices that've been around since 2012. They're portable laptops that run full windows, with detachable keyboards and a touchscreen + stylus.

Here's the iPad Pro, a device that runs iOS, that has a sold separately keyboard (no trackpad) and stylus. If you add it all up, it's more than a Surface 3 + accessories.

How they get away with this stuff evades me.
