This is one of the most gratuitous and condescending replies I've seen on HN. You don't know anything about me, so why would you insult my intelligence?

Computers are very hard to use for people outside of our bubble. Changing that is a major contribution to society and far more than a "wow factor". Seeing disabled people use an iPad is an amazing site.

I'm not interested in ranking ligt bulbs vs iPads, it servers no real purpose. And I'm not particularly interested in having a discussion with an asshole, but I wanted to point out how absurd it is to call something that opens doors for so many people as merely a "wow factor". You are not likely in a position to understand much beyond your own narcissism.
