I'm looking to get the Lumia 521 next Saturday! I currently have the Lumia 710, but it lags when when I'm doing heavy multitasking. Watching an HD MetroTube video while having incoming FB messages and Twitter notifications, and maybe some Zune music or a game background downloading causes the phone to stutter or freeze up sometimes. I'm hoping the 1 GHz dual core processor and WP8 in general will help that. Also there's a few apps that simply don't have a WP7 counter part. I was going to start a new thread to ask a couple questions about user experience but I'm gonna drop them in here because a lot of people interested in this phone will probably look here first anyway.
-How often does the 512 MB RAM become a problem? I'm not much of a mobile gamer, but when I'm at work I love to kill time when I can. I know games like Spiderman won't work because of the 1 GB restriction and I've heard mixed experiences with the GBA emulator. Also, Asphalt 7 apparently keeps switching from available to not being compatible with the 520. Are there any other games or apps that don't work with the 512?
-Snappiness. Anyone had experience with this phone lagging? Any little thing from the keyboard freezing, to the home button not responding or videos getting choppy. I know the phone looks fast and fluid in demos because the presenter isn't really doing anything. But when multitasking and downloading games, music, etc does the phone ever start slowing down?
-How does the $30/mo Walmart plan work? I'm currently on T-Mobile's "Monthy 4g" after I bought my phone outright and pay 50-60 a month depending on how much 4G data I need. Since I almost never call anyone, a $30 plan for unlimited everything except for 100 minutes is way too good for me to pass up. How does that work since I'm already a T-Mobile customer?
