The iPad, Open vs. Closed, Geek vs. Normal
Eric Sink "writes about the coming change in computers:
Computers, by and large, are still designed for geeks. This is why we all buy T-shirts that say “No, I will not fix your computer”. The genius of the iPad is that it cannot get things like viruses. It is a closed platform. You can’t put apps on it. You can’t write and distribute software for it without Apple’s permission. This is why geeks hate it and normal people will love it.
I think he nails it.
