I like this Macalope column from Macworld, reminding us all how wrong all the pundits were in advance of the iPhone (and quite a bit of the dumb stuff that’s been said lately about the rumored Apple tablet). The best part though is his insight that the reason Apple has succeeded with the iPod and iPhone is because those two technologies each had a killer differentiating feature that made them able to disrupt an existing market.

if and when it appears, will have some differentiator that makes it a compelling purchase. The iPod replaced your CD collection, the Apple TV would like to replace your DVD collection (but you won’t buy one), and the iPhone, obviously, replaced your cell phone. The tablet (insert caveat about its existential dilemma) will turn another industry on its head. The problem with the JooJoo is that it has no hook, no ecosystem. It doesn’t act as a compelling replacement for anything you have.

One thing that I’m hoping for (but that I think there’s very little possibility of due to the likelihood that they’re going to base it on iPhone OS) is some kind of personal diagramming application. I’d love to be able to add some programmatic heft behind the diagrams I draw of data models, applications, etc. I’d love to be able to put data behind some stuff, or draw things that can go right into a program like OmniGraffle

If my own little personal BS grammar of pseudo UML could get programmed out pop-n-fresh automatically into some ActiveRecord models right after I drew it freehand, I’d be one step closer to some right-brain techie Nirvana.
