I think madmaze is correct about the difference between "ubuntu" and "ubuntu for phones". You might also be interested to know that Canonical is going to release their "Porting Guide" tomorrow. It looks like they are going to help people port it to other devices, even if they aren't going to do it themselves. So, if it doesn't support the Transformer yet, it might soon.
