They're regularly lifted and carried away here in Uruguay, one police officer said:
""ATMs are still being stuck to the ground with glue," said one visibly angry commissioner yesterday morning (March 22nd), investigating the unusual theft of yet another ATM, which was completely lifted by thieves, who took it "like a bag of brownies". This time, they "lifted" the cashier that was installed in 4896 between Ariel and February 28 streets, just two blocks from the Sayago mall , and took it away after opening the glass door with a magnetic card."
Plus, they're error-prone, I've been victim of such an error several times (the ATM failed to give me the money but withdrew from my account, which SHOULD NEVER HAPPEN), in one of the cases I never got my money back (from Bank Boston Uruguay, which is now Banco Itaú). I'm of a mind that, for small amounts of money, you're better off having it "under the mattress" that in a bank (see: Cyprus, unresponsive banks, etc...). We've had a Cyprus-like bank freeze here in Uruguay, and much worse than Cyprus in Argentina (they forcibly turned their dollars into worthless pesos a few years ago (3) ).

Edit: by the way, the faulty ATM in my case was an (old) Diebold machine. So you can imagine I wouldn't trust one with my vote either :P , though I sadly do have to trust them with my money. (fortunately, voting is still manual in Uruguay).
