In reply to Enty:
Having played with one of these (NIkon V1) I think they are quite expensive and the picture quality is not that good, focusing in low light is less than accurate, although in bright light it is very fast and accurate. The shutter speed does feel SLR-like.
Attached via an adaptor to a Nikon 300mm F4 lens the magnification of distant small birds is amazing (c 900mm 35mm equivalent), but you need decent light again.
The auto ISO is frustrating to say the least. I would look to the Sony equivalent given your post, or buy another SLR.
