Do you use your NEX 3 or 5 as your primary camera?

NEX 3 is my primary camera, my only digital back-up is a truly awful Sony P&S (i bought when money was really tight). Occasionally 'go back' and run a roll of film through my SLR - a Pentax LX, but this is getting less and less frequent - nowadays i am far more likely to use my old Pentax lenses on the Nex - especially my favourite, the 'm' series 85mm f2
