It's funny to talk about the 20 year old hackers who didn't ever have the experience of installing Word Perfect 5.x from 30-40 floppies, but let me tell you that those kids are going to feel just as old pretty soon. My daughter, who is about to turn one, is puzzled by why my Macbook Air doesn't do anything when she touches the screen. She doesn't recognize my dad's old Treo, which he gave her as a toy, as a phone, but will put a thin slab block up to her ear. We don't have cable at home, so she watches all her shows on Netflix and iTunes.

Looking at them like this reminds me how terrible they are -- ergonomics isn't Apple's strong suit. Give me a cheap Logitech mouse any day of the week.

Bizarrely, Apple's dedication to the "simple" idea of not having a second mouse button results in far more uncomfortable and unintuitive interfaces, featuring an ever increasing melange crazy gestural shortcuts.

It's a pleasant surprise to see my old power supply article on the front page of HN today. I'd never given much thought to power supplies before researching that article and there's a lot more to their history than I expected. In particular, Robert Boschert seems like he should be a HN hero for running a startup from his kitchen table that had a huge (disruptive?) impact on the power supply industry.

There are a bunch of comments below about wall chargers. I investigated wall chargers too - see http://righto.com/charger - and there's a lot more inside them than you'd expect.

Let me know if you have any questions.
