Its very simple; they are launching devices that are affordable for people in emerging markets too... For example, Galaxy Mega gives you somewhat the bells & whistles of a Note(II) at a fraction of the cost (and specs)...

This is exactly what any sane OEM should be doing; understand your markets and don't expect people to suddenly find the cash for your flagships so give them a suitable compromise...

Some people berating them for just coming up with garbage need to think in terms of $$$ and understand this device isn't targeted at you specifically...
