I would love to try loading this on an old Samsung Captivate I have laying around. They need to find a way to make loading these operating systems as easy as it is on a PC; actually, that goes for all smartphones. Users should be able to take the hardware and load up Ubuntu, WP8, or (shudder) Android, if they so choose. And it shouldn't be an overly complicated process that voids hardware warranties or likely bricks your device.
I've said it before, and I'll say it again: Android fragmentation will eventually harm the platform. I know it sounds crazy, but OEMs are making it way too complicated to stick with Android. My Samsung Captivate wouldn't sync with my computer because the Kies software only worked for Galaxy S II and III devices, so there was no way to back it up. You can't update to the newest software because the manufacturers block it. If Ubuntu gets it right, I don't see any reason they can't find a place in the mobile handset world alongside the other offerings. I hope they do.
