Default Thing I'm gonna try as soon as I get my SGS2 next week

I have my SGS2 on order and am so excited, that I actually read the user manual pdf in anticipation. These are the improvements that I could see:

Create folders in the apps list
Turn the phone over to mute an incoming call
Tilt to zoom a website / picture
Photo editor app (although this is on the SGS1 Samsung apps)
Video maker (also on Samsung apps)
Tasks app (not sure if this syncs with Google Tasks)
Wi-fi direct (ad-hoc wifi mode built in)
Polaris office
Power saving mode options to automatically turn stuff off when the power is low
Other Motion settings

Can't wait to try these out! :)
