You overestimate the level of investment the average person can and will make for these freedoms. People buy Kindles because they work (and are heavily marketed), they buy Apple because they simply work, and will keep preferring windows to Linux until Linux offer a easier barrier to entry.

Microsoft will (almost already has) loose its advantage to Apple before it loses to Linux.

May be in the US (as Apple products are cheaper and people are dependent on iMessge)

Rest will remain on pirated windows or linu.many often don't even use computer.
