Everyone forgets about Nokia's triumphs of open-ness: the 770 and the n800 Internet Tablets.

These are not phones, but rather small computers running the same type of processor as the iPhone.

The operating system is directly based on Debian, and the distribution is called Maemo. Nokia actively supports this community, and software gets ported from other linux architecture all the time.

There are only a few proprietary components on the whole system and they are: the wifi driver, Adobe Flash 9 (so you can watch those Youtube videos the way god intended) and Skype (phone service anywhere within wifi range).

Much of the software coming out for the internet tablets includes iPhone-like tricks, like kinetic scrolling and such, so there's no dearth of UI candy.

The wifi card on this one is pretty decent, outperforming some laptop miniPCI cards, and still being ultra low power. These devices also, of course, also come with bluetooth. This is how you can pair it with a keyboard, a GPS unit, or a cellphone for data connectivity (you can also have the tablet dial your phone by selecting a contact in a PIM).

Ubuntu is planning an Ubuntu Mobile distro, which will be able to run on the n800 (at least). There's still great software coming out, and a healthy community, so this isn't a complete niche product.

Disclaimer: I'm a proud owner of a Nokia n800 and it has brought me only joy and utility.

Actually, there is absolutely no problem.

A gram is defined as: One millilitre of water is 1 g at 4 °C. A kilogram would be a thousand times as heavy as that.

You can see that this definition then depends on the defintion of the metre, which has been set to be: The metre is the length of the path travelled by light in vacuum during a time interval of 1/299 792 458 of a second.

For many decades no one has depended on these original metal measures in Paris, and it would be absurd to do so!
