We've already seen several instances where low-memory Windows Phone devices like the Lumia 610, which has just 256MB of RAM, simply can't run certain high-profile apps. But just how bad is the problem? AAWP crunched the numbers and found that of the 86,292 apps currently available in the Windows Phone Marketplace, only 1.6 percent aren't compatible with 256MB phones — which is less than Microsoft's claim of five percent. However, that number does increase a bit when you look at the more popular apps. Of the top 10,000 downloads in the UK, 4.6 percent are incompatible with low-memory devices, while 6.4 percent of the top 1,000 apps won't work.

Unsurprisingly, a large number of the incompatible apps are games, with likes of Plants vs. Zombies, The Sims 3, and Earthworm Jim among them — though Windows Phone Tango owners should at least be able to play some Angry Birds on their phone soon thanks to a specially optimized version of the game.
