What does the 640 have that the prior models don't? I think the Lumia line up is getting rather crowded. The current selection seem to use the same chipset (though some are dual cores, others quad cores).
How does this differ from the 830?
Cheaper than 830
Better screen and camera than other mid/low windows 8.1 devices
It just seems so crowded with a bunch of other models that are quite similar.
Why are they sticking with outdated chips for these devices? They could at least put an SD615 in there.
I'm really looking forward to the 640. I'm wondering why the XL didn't get LTE when the 640 did? I'm more interested in the XL at this point but the lack of LTE is a bit concerning.
