Yes, under the subscription plan, the company is responsible for reasonable device replacement when they fail (if not due to abuse, etc).

That's why the subscription plan costs more: pure subscribers are subsidizing device replacement costs (perhaps for users other than themselves).

Under the ownership model, devices come with a 1-yr minimum warranty (we may service other components for free longer, e.g. harddrive has a longer warranty from vendor -- we're still sorting out how to apply that).

Under the lease model ($10/mo) or under the 1yr warranty for the ownership model, yes.
