Many people here seem to be confused and think that you dont need a task killer app for the Eris... YES you do. People will argue that Android is Linux based and that Linux reallocates memory as needed. This maybe true but it is this EXACT process that slows down the Eris and causes even more lag than you already have from the outdated old CPU. This is proven because anyone can confirm that once the Eris reaches 30mb of memory the entire phone starts to LAG even more than normal and under multitasking the phone becomes ridiculously slow at times all due to this memory reallocation process. This has been 100% confirmed. This is the MAIN reason why you need task killer apps, to keep your Eris memory free so that apps load fast instead of having the Eris reallocate memory and THEN load the app into memory. Not only that but when the apps you ALREADY have loaded into memory need MORE memory this reallocation cripples performance and again causes more LAG. Some people simply cant understand this....this has been 100% proven. Phones like the Nexus One are so fast that this memory reallocation process does not noticeably impact its performance.
