Thank you for the clarifications, GeneralAntilles. I understand the need for companies to protect their trademarks. I also would not be comfortable buying a knock-off. I would consider buying an alternative to N900 running the open parts of Maemo on a 4.3-4.8'' screen though...

I am curious if it will be possible to run N900 applications on Aigo or on Optima. If they sell well (because of their larger screens, better price, or whatever), then developers will have more reasons to write for Maemo, right?
