He didn't ban the Galaxy S3. Nor the iPhone 4S. Nor the new iPad. Nor the latest Samsung tablets. It's a "win" for Samsung because they'll earn a slightly bigger reward, but that's it.
AFAIK, you can't download and install it on your phone. A given carrier / manufacturer must talk to them, then they'll tailor the OS to a model, and then the users who buy that specific model can get Ubuntu. This is not a product for the end users, but a way for manufacturers to add value to their handsets.
They had the dominant smartphone OS AND the dominant dumbphone OS. They had an experimental high end, Linux-based OS that was almost ready to retake the top spot in mindshare. They had the best development tools, which would allow one to target those 3 OSs simultaneously. And they were developing this new Linux-based dumbphone OS that would be created around those tools.
Now they have Windows Phone.
Actually, if this graph is to be trusted, it's very far from an exponential growth. You can see two breaks: one at about -5000, where the population started growing; and one at about 1700, where the growth rate increased dramatically. Also a hint for another, more recent break (~1950?), where the growth rate increased again. (Note for the mathematically impaired: an exponential growth means a straight line in a log graphic. You can divide this graphic in 3-4 different straight lines, so you have 3-4 different growth rates at different points in time)
Updating a Galaxy is impossible (bar rooting) without OTA updates which are Carrier Specific. Should your carrier not be bothered with a phone/tablet that they offered 9 months ago you will never get updates regardless of whether every other carrier in the world has an update.
Actually, it's NOT impossible. Search for "Odin", and get the firmware files in
Asking for a 2.3'' touchscreen is nuts. I'm asking for a 4-4.3'' high end phone. Even a Galaxy SII (arguably the best of last year's dual cores) isn't 100% lag-free, the browser could be faster, the resolution isn't impressive anymore (they could use a DPI similar to the Galaxy Nexus, or even bigger, and have a qHD/720p screen on 4.3 inches). I want the phone to fit well in my pockets; when I use it, I can handle the "small" (which was considered "huge" only 2 years ago) screen. It's not like I can't see individual pixels on the current screen.
I'd rather have the same screen resolution with a high DPI in a reasonable (4-4.5'') screen size than with a low DPI in a huge (5-6'') screen.
