With the announcement that Microsoft has updated Windows Phone 7.5 and reduced the system requirements, making way for low-cost devices running on only 256MB, many developers are wondering what impact this will have on their apps.  Rumors were flying after the announcement that there would be no support for Tasks and Background Agents on the low-end devices, but  in a recent interview, Justin Angel from Nokia explained this was not the case:

Background tasks aren’t meant to provide apps with core functionality in Mango. There’s a hard limit on 10 background tasks that’ll cause the 11th+ background task to fail, and users can capriciously turn background tasks off.

-- Justin Angel


What does this mean for users?


Users will likely not notice much of a difference, until it comes to the 11th task.  Even then, Microsoft has found a nice way of letting users know they've reached their Background Task Limit by taking them to the background tasks page in settings.


What does this mean for developers?


Most likely, developers will end up spending some time adjusting apps for each memory set (at least those who are concerned about having their apps run on ALL Windows Phone devices).


Of course, all of this is just a temporary problem, as Windows Phone 8 "Apollo" will likely bring more memory and greater background task capabilities with it to Windows Phone devices.


UPDATE:

Analysts agree that a mix of emulators/simulators and real devices are necessary to optimize your mobile app testing - learn more in this white paper, brought to you in partnership with Sauce Labs.
