Phil (thanks for doing this!),
1. What's your thoughts on the lock screen pages? To me it seems to negate any "security" at all, since now without knowing the passcode you can see the person's emails, texts, etc.
2. How's the screen compare to: iPhone 5, HTC One X, Galaxy S3
3. Can you post a speed test?
4. Can you do the following and report how it seems? On the homescreen of an iphone, swipe your finger back and forth as fast as you can and note how much lag (or lack of a lag) there is in the in the icon movements relative to your finger then do the same on the Nexus 4's app drawer
5. Can you use a few apps on the Galaxy Nexus and the Nexus 4 side-by-side and report how the two phones compare?
Thanks!
