Standardized Laptop Charger Approved By IEC 289
Sockatume writes "The IEC, the standards body which wrote the phone charger specification used in the EU, has approved a standardised laptop charger. While the 'DC Power Supply for Portable Personal Computer' doesn't have a legal mandate behind it, the IEC is still optimistic that it will lead to a reduction in electronics waste and make it easier to find a replacement charger. Unfortunately the technical documentation does not seem to be available yet, but previous comments indicate that it will be a barrel plug of some kind." I wish they'd push a yank-resistant and positive-connecting plug along the lines of Apple's MagSafe.

Fair enough. I wonder how much they patented. If the patent just magnetic based, then presumably you could add an extra pin and only switch on the PSU when you get the correct command over some 1 wire bus protocol.
Or do what the USB charger people do and only provide power if there's the correct resistance across some of the pins.

It would be easy to smash it across the EU on the basis of prior art and obviousness. There were already magnetic power connectors; I have a magnetically-attaching cord here which goes to a waffle iron which predates MagSafe. There were also already autonegotiating power connections before MagSafe. Putting the two together on any power cord is obvious and was only a matter of time. If the government wants the patent invalidated, it shall happen.

Two things come to mind: 1) The bottom line. Many companies don't always do the little things because it takes time and money to do things. I'm pretty sure an engineer from another company came up with great ideas but they were cut in planning/development. Apple will spend years on a product before releasing it and they will charge enough to make this strategy work. 2) Featuritis. Many companies focus on too many features. This is related to #1. Following the history of Apple, their products never have the most features. Apple seems to focus only on a handful of them and get them right before adding new ones. Geeks here don't appreciate that as Apple will never win the bullet point count, but for the average consumer they are less impressed with numbers of features than working features.
Take for example, the original iPod that synced automatically when you plugged in the cable. I think it was at Jobs' insistence that this be a 1-step process. Now doing so isn't technically difficult, but it takes coordination between hardware and software. It also required a philosophical change away from file/directory based transfer to one based on metadata. For example, most people don't care which directory/subdirectory their favorite songs where located but what they were (songs by The Rolling Stones, blue-grass songs, etc.). Now other companies might have been focused on other features like playing every format from Ogg to WMA or an equalizer with 11 bars, etc. Apple concentrated on making the UI simpler for the average consumer.
