Actually chromium-browser isn't entirely free software:

Android doesn't even let you adjust the font size which is an essential part of the user interface:

You are right.

All the software (including drivers) is FOSS. Of course the GSM chip still tracks your rough location in order to work.

I'm currently using QtMoko (which is based on Qt Extended Improved which is forked from Qt Extended) on my Neo Freerunner and I have no idea why Nokia stopped developing Qt Extended as it seems to have a lot of potential. It has a lot of menus just like my previous Nokia phone, but you can simply add the applications and settings that you visit regularly to the favorites section. It also has handwriting recognition which I think is neat.

Porting software is not just copying the code. Popular software does in fact get ported. A good example of this is the Openmoko phones, which contains a lot of ported free software (e.g. FBReader, Midori and Pidgin). Porting non-free software however is impossible unless the developer chooses to do it.

Nvidia only needs to release the source code of one of their drivers (say a Windows driver), and the GNU/Linux developers would create a driver for them. That is how openChrome was born (VIA only provided irregular releases of the code but that was enough to create Unichrome which was forked into openChrome).

What I tried to explain was this:

1. If you use Windows all the hardware will be supported (usually) by proprietary drivers which will only be supported for at most a few years, so new features will not be added even if the hardware can support them. Some hardware is not supported at all or only partially supported on GNU/Linux by proprietary drivers, since the companies don't think it is worthwhile for them to make an effort to support GNU/Linux. These companies want the users to buy new supported hardware instead of adding support to existing hardware. This is part of the reason why I think proprietary drivers are bad.

2. If you use GNU/Linux and use hardware that is supported by free drivers, then chances are that newer common features (like connecting to an external monitor with a 16:9 resolution) will be implemented. This is one of the reasons why I think all drivers should be released under a free license.

Here are some examples of developers of the software controlling the users of the software using proprietary software:

1. Free software, unlike proprietary software, can be ported to other operating systems (and to different architectures). Proprietary software will usually only be ported if the developer wishes to do so (e.g. if enough people use the operating system), which is why for example Adobe did not release a version of Flash for FreeBSD or for the Openmoko GNU/Linux distributions.

2. Nvidia is unwilling to add VDPAU support to the GNU/Linux drivers of their old graphic cards even though the Windows drivers support the equivalent technology. So if you want VDPAU on GNU/Linux you need to buy a new graphics card, even though your card should be able to use VDPAU if Nvidia decides to support it.

3. The VIA Unichrome Pro graphics card does not support a 16:9 resolution when using the proprietary graphics card driver on Windows XP, so if you want to connect a Windows XP computer with this graphics card to a 16:9 monitor without seeing a distorted image, you need to buy a new graphics card. The reason for this is that VIA stopped supporting the driver in 2007. The free driver on GNU/Linux called openChrome on the other hand supports 16:9 resolutions such as 720p. If someone didn't know about GNU/Linux, they would probably just buy a new graphics card, even though their card might actually support a 16:9 resolution if the graphics card driver developers decide to support it.

The whole point of a free distibution is not to use or recommend proprietary software as proprietary software is viewed as unethical since the developer of the software controls the users of the software. The distro Trisquel is based on Ubuntu so you can get most of the help needed from the Ubuntu forums. The distro also has its own forums. The main differences from Ubuntu are a rebranded Mozilla browser which never suggests the use of Adobe Flash and instead uses replacements such as Gnash, the removal of Ubuntu's Multiverse repository as it contains non-free software and a Linux kernel without any non-free binary blobs. Note that since the Linux kernel contains non-free software it violates its own license.

And Google isn't doing anything to rectify the situation despite the following bug reports: http://code.google.com/p/android/issues/detail?id=4547 http://code.google.com/p/android/issues/detail?id=3382 and http://code.google.com/p/android/issues/detail?id=5876 Android lacking adjustable font sizes is inexcusable. Android's font size is tiny on small screens. When I installed it on a friend's Neo Freerunner the first thing my mum noticed was that the fonts were tiny. I can choose a different distribution on my Neo Freerunner, but someone who buys an Android phone without root privileges cannot.

The problem with Android is that Nokia will need to compete with other manufacturers that sell Android phones. However, none of the major manufacturers are selling Gnu/Linux phones (discounting the N900), so Nokia could have chosen it instead of Windows Phone 7.

...was that despite their large market share in mobile phones, everyone was running different versions of Symbian OS and thus couldn't run the same applications. Had Nokia let its users upgrade their OS this problem would have been solved, because by 'forcing' people to buy a new phone to get a newer version of an OS there is always the danger that the users will buy from a different company. Of course Nokia could have also taken more steps to keep its current users pleased, like developing more software (e.g. an .ePub viewer).

The Openmoko phones were released before the N900 and they provide more freedom as the drivers are free software as well.

This (my previous comment) also holds for Epiphany.

Actually the fast and free (LGPL licensed) browser Midori supports WebM on Youtube and both H.264 and Theora on Dailymotion. So technically you could say that it supports all three html5 video formats (WebM, H.264 and Theora).
