I often find this is the biggest obstacle with moving people to FOSS solutions. People want an alternative to Photoshop, so you show them Gimp, and they immediately get frustrated because they try to apply the logic and design philosophies of Photoshop to Gimp. People want an alternative to Windows, so you show them Linux, and they immediately get frustrated because they try to apply the logic and design philosophies of Windows to Linux. And then when it doesn't work the same way, then obviously that is a deficiency of the alternative, and not simply them having to learn a new way of doing things.
