Lower noise at high iso means exactly that. Higher maximum iso means exactly what it says too. However, just because a camera has higher maximum iso doesn't mean that it's usable. Lower noise at high iso and higher maximum iso do not mean the same thing.
A larger sensor also gives the benefit of shorter depth of field, so if you were looking to do portraiture with either camera the nex-5 would give a more out if focused background easier (though a faster lens with a long focal length would be needed. The 16mm lens won't give you much bokeh).

Many reviews say that the user interface for the NEX-5 is really annoying. Is it really annoying? I would like to upgrade from my point-and-shoot camera to the NEX-5. How is the user interface of NEX-5 compared with the regular point-and-shoot camera? 

P.S: I never use any DSLR camera.

Hi Der Auerhahn, yes, a few of the differences shown are a bit redundant, however, we don't use the redundant differences in our scoring, so they are there to help people understand the differences between the cameras.

Thanks for pointing out those aspects of the PEN that we missed!

This "test" is pretty stupid as several aspects are accounted for several times:
- Lower noise at high ISO + Higher maximum ISO
- Larger sensor, which is actually no advantage in itself, but simply enables higher ISO (already accounted for twice) and higher dynamic range (accounted for separately) again.

Several important aspects in favour of PEN are also missing:
1. Lenses and body are reasonably balanced, whereas NEX uses a tiny body with huge lenses.
2. NEX misses controlls and can only be used via menu.

The NEX doesn't have built in image stabilization (as far as I'm aware). Some of the lenses available for the Sony do have image stabilization, but many do not. The advantage of the Olympus is that you get image stabilization with every lens.

This is silly. Sony uses optical stabilisation. It is unfair to say NEX doesn't have any image stabilisation.
