So after using 2.0 for a while now its clearly a really solid update. For me the star of the show is the Messaging app - it really is better than anything else I have experienced on other tablets.
The Calender app is great, mine is linked to my corporate exchange and it pulls the facebook and linkedin profiles of everyone I'm meeting that day, a really nice touch.
Apparently video calling has improved but I didn't really use this before. May give it a go with my brother.
Predictive text is obviously a real bonus, but with the ability to use my Torch keyboard via bridge, I'm not sure how much i'll be using the on screen keyboard for anything larger than web input.
The one thing that is obviously missing is dedicated BBM. It really is disappointing to think they have been working on this since they started to develop the Playbook, and its still not ready. I'll guess it will launch with the first round of 'BB10' sometime in Q3/4
Overall very impressed with the update, it starts to show the Playbooks true potential. Would have loved to see how if would have fared if it launched with some of these features.
