Windows phone 8 is awesome and a refreshing change from Android. As regarding apps, essential apps are available and there are some games such as Dredd & Zombies, Reaper, royal revolt, etc. Temple run is running without a glitch, but its true that it have way less apps & games than the android or iOS.
The hardware is robust with Dual core processor and 512 MB RAM. The phone's interface is pretty straight forward and never lagged even after i have installed 100s of apps.
The only downside is battery performance is a little below par with almost a day with light to moderate usage. If you do heavy usage like 3G browsing, Videos or Gaming it hardly lasts for 4 hours.
Overall it's a decent smartphone experience under 8K, thanks to Nokia's strong spec and Microsoft WP8. Buy it, you will love it...
