Even it is the best technology ever, if not enough people buy it the company will go down very quickly.
I suspect that they spend a lot for content, because growing organically is almost impossible if you target entertainment with an rumored $2k price point. Nobody would buy that if the're only a few apps, even if they're unlinke anything else.
Then, as the next step they'd need to provide a good developer experience. Needing a PC for a device that aspires to disrupt the industry and replace other devices, won't cut it. It would need to run on the device.
I hope the content is really good and worth the experience, otherwise this is useless. But I am still afraid that if they have to create their own content it might not make sense as a business, why people wouldn't be interested in created content for the next audiovisual platform?
I don't think the PC is the problem here.
