It seems that Microsoft is very keen about making its mobile operating system (Windows Phone) a great success. The company has been very optimistic about its forthcoming versions of Windows Phone mobile operating system – Windows Phone 7.5.1 (Tango) and Windows Phone 8 (Apollo).
Windows Phone 7.5.1 i.e. Tango is anticipated to be released sometime during Q2 of this year, whereas Windows Phone 8 (aka Apollo) will follow in the Q4. Experts and analysts believe that these two revisions of Windows Phone won't necessarily supersede each other. Instead they both will co-exist in the market as we head into 2013. This means that both the upcoming versions will be quite important to the future of Windows Phone, despite their minor and major tags.
The two upcoming versions of Windows Phone – Tango and Apollo – will create a fork in Windows Phone i.e. a sort of fragmentation instead of overlapping each other. According to experts, Windows Phone 7.5.1 will optimize the software for lower memory requirements (256 MB instead of the more typical 512 MB) and will be targeted at entry-level devices, primarily made by Nokia. Apollo, on the other hand, will share core technologies with its desktop- and tablet-based stable mates.
Stephen Elop, CEO of Nokia, said, “Android is too fragmented and we do not want to create the same thing with Windows Phone.”
