I'd suggest considering a SS cyclocross bike. Far more versatile, much more comfortable, and every bit as cool as a track bike.
As popular as track bikes have become for urban riding, they really don't do so hot in real world conditions (potholes, rain, pavement imperfections, etc).

That's just me, though.
Of the 3 posted, the Pista is the one I'd go with (add at least a front brake - riding a fixie with no brakes in an urban setting is just stupid IMO).
