I agree with you that the locks aren't the best possible. Skyhooks wouldn't be a particularly great choice for an outdoor mall or a shady alleyway (they're not waterproof anyways), but they're perfect for cafes, small businesses, meetups, etc. I haven't heard a single report of a stolen or compromised Skyhook yet, and hundreds have been shipped. I don't think this is as big of a problem as it's made out to be.

Instead of making the entire unit expensively heavy, we opted to provide a way to bolt the unit onto something else, via 4 thick screws on the bottom of the unit with a heavy mounting plate, and supply that with purchase. That way, the ATM is either portable (a lot of people like to take them to Bitcoin meetups or swaps), or you can optionally secure it to something very difficult to steal. That way, you get a choice.

If the unit is removed from the wall, the unit detects that it has been powered off and locks the system, requiring the operator password to unlock it. It's not perfect security, but it's pretty good.

Skyhooks don't have protection from Denial of Service attacks from God yet though, unfortunately: http://www.coindesk.com/arizonas-first-bitcoin-atm-struck-li...
