Just noticed this thread. No real lag on the phone but have about 53 apps installed, leaving about 49mb of memory after caches have been cleared. I do use ATM--but manually kill every now and then, with auto-kill turned off. I'm going to purge a couple more highly-rated free apps that I thought I would need but really don't use like Superpages and HandyCalc. Most other users on the forum seem to have a lot more memory left on their phone. There's also a difference between the memory that's checked via the SD card and phone storage setting on the phone vs. memory that's visible in task managers that fluctuates rapidly after killing apps. The 49mb number is the one on phone storage setting.
