Was looking to upgrade my old Ixus P&S as I recently bought a new DSLR and love the upgrade in image quality... After a lot of research was seriously thinking of buy a Sony NEX and then came across this deal at Argos.
The NEX-3NL has been replaced by the a5000, but if you're not bothered about wifi connection or an increase in megapixels (but not, necessarily, image quality), then you can save yourself £100 by buying this model.
It's not quite as small as the RX100, but is cheaper and has a bigger APS-C sensor. And... I've just ordered a £20 adapter from the US so that I can re-use my old Canon FD lenses! So, even though I will only use this as my P&S in the future (it's very dinky for a mirrorless camera), I will still be able to use it for some 'serious' photography.
