First up, here’s a look at the re-organized emoticons available when typing on WP8 (text/email/tweeting/browser/whatever).
Notice that instead of a big list, they’re organised into these tabs (are tabs metro?) that make it easier to see more emoticons of different types and a much wider variety too.
As mentioned, not a major feature but lots of small improvements that improve user experience.
Next up, an early look at some of the new apps.
Here’s MetroTube, currently available for WP7 but tweaked for WP8
Finally, OTA updates for WP8. This will allow you to do this over WiFi or cellular. I’m gonna stick with PC updates. As seen in the video, the update didn’t work. A known error was mentioned. I hope it actually works in future.
