If you have a BlackBerry 7 device and frequently visit Youtube, you likely noticed a change in the formatting. Yes, Youtube has now rolled out their HTML5 layout for BlackBerry 7 devices. Of course, this does come much later then other platforms but either way it's nice to see it being implemented finally and much of that can be credited to the work that was done on the BlackBerry 7 browser by RIM and their Torch Mobile browser team.
Sadly, if you're not running BlackBerry 7 you are indeed stuck with the older mobile layout and won't be able to take advantage of the higher quality streaming and better formatting Youtube now offers. But you can add that to the list of reasons why you need a new BlackBerry.
