High-profile Windows Phone apps are unable to run on the Lumia 610 since it only has 256MB of RAM. AAWP put together some numbers and found out that of the 86,292 apps in the Windows Phone Marketplace, only 1.6% are not compatible with the 256MB phones. This number increases when you look at just the top 10,000 downloads in the U.K. In that sample, 4.6% of the apps are incompatible with the Nokia Lumia 610. And 6.4% of the top 1,000 apps will not work. This includes mostly games like Plants vs. Zombies and The Sims 3. However Windows Phone Tango owners will be able to play an optimized version of Angry Birds on their phone.
