Nokia India just announced their Lumia series of smartphones which come with the brand new Microsoft Windows 7.5 operating system (OS). This partnership between the two giants is something that everyone is talking about. Nokia, as we all know, are known for the build quality of their phones, i.e. the hardware; on the other hand Microsoft are the makers of the most popular OS in the world, i.e. Windows. And when two such successful brands collaborate, magic is bound to happen.Nokia has come out with two phones in their Lumia series, the Nokia Lumia 710 and the Nokia Lumia 800. Both phones come with the Windows 7.5 OS, which is definitely the talking point about these smartphones. A revamped interface was one major thing which the consumers were looking for, from Nokia. And now with the familiarity of Windows and the power of Nokia, the Lumia series might just change the way we perceive smartphones. The Nokia Lumia 800 is the superior one among the crop and is aimed at the high end user out there. With a 1.4 GHz processor, 512 MB RAM, 16 GB of internal storage, an 8 MP camera, a 3.7 inch Gorilla-Glass ClearBlack display, makes for a power-packed gadget which will attract even the biggest mobile geek to consider giving it a shot. A seamless body design with no external buttons on the display gives you the largest workspace and a sleek design which is really good to look at. The Nokia Lumia 710 on the other hand is pretty similar to the Lumia 800 but it has some differences. It has a relatively less powerful 5 MP camera. The storage capacity is also significantly lower with 8 GB on the Lumia 710 as compared to the 16 GB of the Lumia 800. The other notable difference is the battery size of the two smartphones. But these differences mean that the Lumia 710 could very well be the most affordable Windows Phone smartphone in the market.Whether these smartphones will really click with the consumers will also depend on the pricing Nokia announces. But one thing is for sure, by the looks of it, Nokia has taken a solid step in the right direction in the smartphone market.
