Re: Half-arsed effort so far - at least with the Activ S
I bought an Ativ S over a 920 for 4 reasons.
1. Cost - £100 cheaper than the Nokia when bought outright
2. Size and weight - both slimmer and lighter than the Nokia by quite a margin
3. Expandable storage - SDXC support means I've added and extra 64GB of storage for £40
4. Replaceable battery - this is a nice option to have.
It's just a shame Samsung couldn't think of anything interesting to do with the design. Also 2-4 apply to the HTC 8X
