Not holding my breath. Oh, fine and dandy, a company with the resources can write custom apps or whatever.
In the meantime (unless something has changed that I'm not aware of,) a WP user cannot:
1. Export SMS as text or CSV. Could be very crucial in day to day matters, let alone legal.
2. No call log. You are a lawyer, say, and you can't go through the phone "log" at the end of the day for billing purposes.
3. No HID bluetooth or keyboard connection to a PC. Understandably, not a deal killer for many. But for the Fumble Fingered, like me, this would be wonderful. I use the on screen KB as little as possible, and the speech to text is close to worthless.
4. If you presume an enterprise is running Exchange Server, all the employees use LookOut, all is well. But those who aren't there are in the middle of the battlefield of email and calendaring. Ever hear of CALdav, MS? Oh, wait, even non-enterprise Apple does a better job...........including Outlook integration.
I want WP to succeed. But it has a long way to go. And "It's new," is a poor excuse. The things I mention are instantly obvious.
