Re: Voice recognition
Tried it last night, including send a BBM and an email and setting a calendar appointment with fantastic results, have to say I'm very impressed overall. Lots of very nice little touches to the OS that make it a pleasure to use. The screen's unlock mechanism being responsive even when the screen is "off" is particularly nice I think.
I managed to make the calendar app crash when changing a calendar's colour, and also managed to make the email hub panel flip out a few times ("no items selected" even though two were) but I imagine a lot of this is just stuff that will get ironed out with updates just like any other fruit-based delivery.
One thing I'm very disappointed on is the playbook integration. When you hook up a playbook to it, the playbook has no control over the device - basically the "bridge" is limited to just internet tethering, you don't get the old way of looking at the device's contacts, calendars, messages and so on. But again, perhaps that will be fixed with an update.
Thanks for the pointer regarding sound profiles. You are limited to Normal, Calls only, Vibrate only, Silent, and All Alerts Off. No opportunity to set your own profiles up, and no opportunity for location-based or time-based profiles (yet).
