Never been much of a fan of those "comercials" with everyone being all happy and stuff. Also, i had hoped that Sony would continue to use the XrossMediaBar that they used for PS3 and PSP, but i guess that it's time to move on.
I do like the Share feature. I've been playing Trials Evolution Gold Edition and it's good that I can upload a video of how I beat the track whenever I've finished. This seems to be far better though.
