The Bridge function works perfectly with the Z10 and PlayBook, however like what was mentioned above, some of the features are not the same as it was with the old BB 7 and earlier phones.  You can do the following when you Bridge:

1.  Surf the web

2.  Use apps that require a web connection (such as Facebook, etc.)

2.  BBM

3.  Text

4.  Access files (I didn't know about the video issue, I've never tried)

Lost is your email "mirroring" to the PlayBook, but to me that isn't a big deal because I like reading my email on my phone better.  Plus I have my same email accounts set up on my PlayBook so it's not an issue at all.
