As it turned out, Minitel is a good example of the risks of early adaptation in a limited market.  At launch all the parts required for the Internet were there but their technological capability weren't up to the task, e.g., the 70 baud upload speed, the cost of the parts were very expensive such as the $100,000 per gigabyte for long term storage, and so on.  But the real killer was the fact the market was limited to France meaning it never achieved the economy of scale of the Internet.
