Microsoft unveiled cheaper smart phones

We all know how Microsoft bought Nokia's business earlier this year?. They still made phones with Nokia branded to it,but unavoidably Microsoft has started to brand lumia to it's name.Cool right?.what's more?this phones are really cheap,and has awesome specifications like:
•5mp primary and secondary cameras-a secondary camera with 5mp.hmmhpmm.most awesome for selfies...
•This devices come with framed buttons on screen and not physical buttons.Cutting the cost of manufacturing.. To me I think physical buttons shows many efficacy
• Despite the low cost, Microsoft said the new phone will offer the same Microsoft services that high-end phones do. That includes Skype video calls, Office apps and the virtual assistant Cortana.
•lastly is the dual sim function..
I cheap phone coming this high end function should indulge in more dominance in the tech market.A good example from these list of cool devices is the Microsoft Lumia 535.
