You can already buy those. They seem to commonly be referred to in online stores as ‘pocket wifi’. Just stick a sim card in them and you can manage their settings through any connected device with a web browser.

Besides the other points already brought up regarding this, 2 hours is just too short. Games like this often have long startup times, long intros, etc… and it’s just not enough to get a good impression of the game. At least with demos you get a good vertical slice preview of what you’re getting into.
