The worst thing about it is that the interface lag problems seem to have gotten significantly worse since launch. I've even tried re-installing the firmware, backing up only my contacts, but it now seems common to wait sometimes as long as 7-10 seconds for an app to load, or up to experience up to around a five second lag in keyboard input, especially in search boxes in Safari and YouTube.
