WOW.. this is a lovely deal!!! Its better than Galaxy R. Almost same.. with Moto excellent buld quality, higher resolution screen and better camera. And most of all... better Dev support. No reason not to choose this over Galaxy R.
12K is too much, but 15K is a decent price for dual cores in next couple of quarters... Tegra 2 is a generation old tech. No reason for tegra 2 phones to come down to 15K margin withing a couple of months. And after than even 32nm dual cores would be coming down.
All depends on Samsung Ace 2. That should be the precursor for the 'cheap' dual cores...
