Take the great voice of GLaDOS. Add in a Garmin GPS unit. Mix in some trickery, and you have a sudden need for a portal gun in your Volvo.
Yes, someone at Vanmiddlesworth has created the Portal Glados Voice File, allowing everyone’s favourite demented computer voice to tell you where to buy cake from…

Just… don’t go anywhere that buys incinerators. That test is impossible…

Apple have unleashed possibly their worst kept secret ever.

Apple (United Kingdom) - iPhone:
Introducing iPhone 3G. With fast 3G wireless technology, Maps with GPS, support for enterprise features like Microsoft Exchange and the new App Store, iPhone 3G puts even more amazing features in your hands.

Now, I have already said in the past that I wouldn’t have minded getting my own iPhone, but eventually I turned away, partly because of the excessive cost of the unit excluding the contract, partly the fact that it was a futuristic phone that did NOT have 3G. Now, with 3G, a decent GPS feature among other improvements, it’s enticing. The much lower initial cost is now comparable to other handsets.

BBC NEWS | dot.life | A blog about technology from BBC News | Hands on with iPhone 3G:
Questions to Greg Joswiak about refunds for anyone who has just recently bought the old iPhone were met with little sympathy as he pointed out that news of the 3G version was ‘hardly the best kept secret in the world”.

I do have to say it’s probably not a leaked secret. 3G has been such an asked for and complained about problem of the original iPhone that it was logical for Apple to work on this anyway, and for people to talk about it.
There was no leak. The hype and guessing was just correct on something obvious.
