my long national nightmare is over...my 553 updated yesterday, serial #GLPP37ALxxxxx.
skype and youtube automagically appear on the app bar, no installation necessary. skype works as a text chat right out of the box, and ive ordered the camera/mic, so i'll report back on its quality.
youtube is mostly fantastic - the automatic selection of the highest hd video is fab, and the quality is amazing, but the inability to search, a la amazon, right from the app while still watching a broadcast would have been a nice touch, as well as the ability to sort found videos. still, its availability is very much appreciated from this user and family.
was hoping to find 'video' now as an option in the media app, but the fact that vizio is still updating this set gives me hope that it will perhaps come in a future update.
