I'm not going to argue against abortion or defend fringe groups, but your logic does not follow.
If there was a serial killer who had escaped from maximum security prison several times to continue killing, then by killing him, it would preserve more lives. Therefore, killing someone is in line with protecting all life, because all alternatives lead to more lives lost.
It's easy to say that, but when you take Apples "Less functional" product and set it next to a "More functional" product you can really see a difference.
No, you really can't. For example, the iPod, which you mentioned, isn't anything particularly special (for the vast majority of models).
See, you completely miss the point. The innovation with the iPod wasn't the iPod, but iTunes. 99-cents a song for a very large selection, just plug in your iPod and the friendly interface guides people to put music on it. Other companies made you purchase music elsewhere and import it into their syncing software. What Apple saw was a gap--not one in the mp3 player technology, but in the hurdles people had to jump over to get music on them.
