Thanks, I'll pass on that info to her.
If that extra weight is due to extra battery then Nokia have got it right, whereas Apple, Samsung et al have got it wrong. I really don't see the attraction of this "thinner and lighter is better". Apart from anything else these razor-slim featherweights are darned easy to lose in your pocket - try doing THAT with an old Nokia N95 or similar! Actually think that the S3 is too darned thin/light and actually quite like the olde-style "chunkiness", relatively speaking, of the Lumias.
That said, I was looking at a Lumia 625 at the weekend - which seemed way too big for me. Just a shame that Nokia decided not to "do" Android - that could've been good.
