Well Juan, I can not say much about this particular camera, I've heard of it, and the way it uses a mechanical switch. Everything can break. However, if you are to often switch back and forth between viewfinder and LCD, there will be more wear, and it is more likely to fail then a EVF or a optical viewfinder would.
A good friend of mine has a tiny Minolta F300 - she's very happy with it. Another recently bought, and exchanged two Minolta A2's because of imporper auto-focusing. Minolta tends to get mixed reviews on quality control, it seems. Now consider this, you are buying a camera that will be hard to service, and especially one with a more or less untested/not widely used viewfinder system, at least to my knowledge. Would you really want to rely upon that?

At least that's how I see it. As I said, everything can break. My two cents; I'd get something more tested and without the weird switchfinder gizmo.
