I looked at all of these before my recent aquisition of NEX 3,...for a while it was 'touch and go' with the NX10/NX11.
Had teh reviewers conisidered the TRUE situation with the NEX it's difficult to see how that camera was not to come out head and shoulders better than the others. The NEX was marked down for poor menu/controls which can actually be radically improved and customised by use of the latest firmware such that menus don't really have to be used,...And, they criticised lack of lenses and adaptors when in fact masses of adaptors to fit just about any lens are available cheaply from ebay.
