the calendar and contact on OS2 seems amazing. I'm concerned that it won't integrate well with my blackberry. I like having calendar and contacts bridged from my phone. Will the bridge calendar and native calendar sync properly?
If you already are using bridge then the native PIM on the PlayBook is not as crucial to have. Native PIM is most useful for people don't have a BlackBerry phone.
It's very interesting for me to find out that my mom is using her PlayBook solely for watching movies (hdmi to big screen tv). My dad uses his to read online news. My grandparents use theirs to play game. The native PIM will help them to use email more often.
