Last time I went through I saw they had removed from one side of the departures and arrivals halls the old machines used with the card and hand "signature", I assume to make room for these 17 machines.
That's likely to create queues for those machines as they sometimes get busy. Personally I am holding off as long as possible with a biometric passport. Don't trust the security of the database at all and will only do it when it's proven secure or becomes mandatory.
