I would highly encourage the kind folks at Google to send our beloved editor a Nexus 4 and a Nexus 10 as well, just to read his whimsical notes on Android and musings on the state of the computer industry.
As for the keyboard, I have found gesture typing to be much more useful on the mobile handset. It definitely helps with one-handed typing (well it actually makes one handed typing possible). On a tablet, or when I have two hands available even on the phone, tap-typing still feels faster, but I really appreciate the added attention to one-handed operation of the phone in many different areas in Android 4.2, an area that Android has been sorely lacking compared to MeeGo Harmattan and WebOS.
As for cloning a device onto another one, can I just point our editor to an application called Titanium Backup. It is a very reliable and effective way of backing up user-installed apps (with all their data) and restoring them on another device. However to use NFC and Wifi-direct to do this... I think you have just given a few people a nice challenge to work on!
