I think hardware buttons is not very expensive. Typical Android phone cost is about $300, price for dumb phone with hardware keyboard started from $30. Hardware keyboard on my Nokia 2630 still works without problems after about 4 years of daily usage. Lack of hardware buttons is on of reasons, why I still don't use smartphone.
