This news can arouse dismay in those OEMs, which produce low-end smartphones. It seems some manufacturers would gladly accept the idea that Microsoft makes soft only for elite devices, as it will leave space for low-end device makers. But Microsoft has not overlooked this field, as its next WP update codenamed Tango is going to be usable also on low-end handsets.
The secret is in the fact Microsoft has decided to lower the RAM requirements on which Tango can run. So the new update can run on 256MB RAM instead of 512, which is the standard RAM requirement for most of the devices. A WP fan Michael Gillet from the UK says the new update will bring folder support on Start Screen and a UI improved specifically for better media control, becoming like notification icons, thus bring in more space on the screen.
This can mean that Microsoft wants to develop software with a more optimized code, thus making it possible to run apps, which previously demanded a high number of RAM. This is bad of course for some manufacturers, whose niche was just in the affordable (not to say cheap), low-end handsets.
