But there have been Android tablets and Linux touchscreens. The article already states that these companies make their own hardware prior to the iPad, and the NovaTouch in the article is based around Android devices. Yet none of them meet the goal here. So clearly the open sourceness of the platforms is not what’s holding things back. The reason I mention ideals is because you came in to the discussion and effectively said “open source would solve this” but it’s such a non sequitur from the problem at hand, especially given the history of the field. You’re interjecting your own belief that the lack of ann open source platform is the reason without actually bothering to understand the problem space involved and the players that exist. Just because the cloud runs on open source doesn’t mean much for this. The cloud also runs on closed source hardware.
