First, the FSF needs to convince us average users need to have control. Why should average users have control over their computer? Isn't this what got us the virus nightmare in Windows?
Uh, because they bought the device? I think the burden is on the other side for taking away control.
I don't think Mac OS X will ever go away from giving you the control it does (and it is quite nice), but Mac OS X is not appropriate on a device like the iPad.
Why isn't OS X appropriate? What is the difference between this and an Air? I saw the presentation, the device sat between the iPod touch and the macbook. What is one OS appropriate and the other isn't?
In fact, I would compare the iPad to the upcoming yet-to-be-made Chromium netbook. The vision Google laid out for their device is pretty much exactly the same as Apple's vision of the iPad. Except that Apple is actually _less_ connected in to your device than Google would be.
"Google's doing it too!" is not a good argument.
Attacking Apple's products is one thing. Why not create your own open source tablet to compete, and let the marketplace decide?
Well, I'm sure it will: https://thejoojoo.com/, though the market doesn't always act rationally, and perhaps the FSF is trying to raise awareness about the freedoms people are giving up for Apple's style.
