Comment 21 for bug 615300

Sorry, no, I think this is a terrible idea.

"Sent from my iPhone" as above at least has some use in that it's a sort-of implied apology for an otherwise rudely short, misspelt, jumble of thoughts masquerading as a real email. However even this I find annoying and offensive when compared to a manually set up "This message is sent from a mobile device and therefore may be brief" (I know it's wordy, but you only type it once). "Sent from my iPhone" to me just reads "Look, I've got a gadget and I'm arrogant enough to not apologise for being rudely terse while I use it".

"Sent from Ubuntu" serves no purpose to the sender (they know they're using Ubuntu) nor the recipient of the email (FOSS was all about choice, I thought, including people's choice to use another OS) so I think it's a absolutely horrible idea. You may argue that people haven't switched to Ubuntu through lack of awareness, my counter argument to that would be that there's already enough ways of publicising Ubuntu, without "hijacking" new users PCs. Not least because if they installed it and found this behaviour by default, then if they're new to Ubuntu and don't know much about Ubuntu and Canonical, they may see this as Apple-style arrogance ("It's my computer, not theirs").
