The lack of a cellular modem in the first-generation device seems like a mistake. Maybe I'm missing something here but Solu give me the impression that they are trying to promote a solution for non-geeks (who find remote desktop use too complicated), based on a ubiquitous computing model where Solu users use Solu and nothing else, yet at the same time they expect users to tether from a non-Solu device which not only breaks the ubiquitous model but is also arguably more difficult to set up than a remote desktop connection.
