The e-gates are for EU passengers only. In all honesty they're borderline useless, both in terms of user experience and advantage over the human controls. A police officer will look at your EU ID for a second, if anything; the e-gate will take at least 15 if not 20 seconds.

The comparison with the e-gates in FCO or VCE is embarrassing, even though those have been built by SITA in conjunction with the Italian ministry of interiors (marriage made in hell if you ask me).

The only difference between FCO, VCE or MXP is their ownership. Whilst FCO and VCE are private, MXP & LIN's managing company, SEA, is owned by the city of Milan and is used as a cash-cow to fund other departments that run a deficit year after year; the result is shoddy investment and sub-par infrastructure; just compare the public toilets in FCO with the ones even in the newest Satellite in MXP to see what I mean...
