Good products get used.
Usage creates dependency.
Dependency is bad.
Therefore, good products are bad.
Since bad products are bad, and good products are bad, all products are bad! You have just plugged in OSX into the syllogism.But the syllogism results in a contradiction. So one of our assertions is wrong. I'll leave it as an exercise for the reader to decide which it is.
P.S. use Picasa on OSX, not iPhoto. And iTunes does indeed suck and I don't understand why someone hasn't written a replacement for it that fits the Sparrow:Mail==X:iPhoto equation. Perhaps I'll take a crack at it.
