I upgraded my Dash to Windows Mobile 6 earlier in the week. It's prettier, sounds better, and they've fixed a lot of little things to streamline messaging and calendaring, etc, reducing some nuisance. But by far the biggest "WOW factor" is the Voice Command application. I can ask my phone, "What is my calendar today?" and it will read it back to me. It will announce the name of incoming calls (over the speakerphone or bluetooth headset, configurable), read the header of an incoming message, I can ask it to dial a phone number, call a contact, play an artist or album in Media Player, read me the list of available artists, read me my missed calls, my battery level, my signal strength, start any program...to name a few features. All of this with no voice training; the speech to text is solid. It successfully knows that when I say (phonetically), "yahn why-check" that it should load "Jan Wasiek." Now, I admit this won't be a huge deal in my daily routine, but next time I'm driving and an email or text comes in, I won't take my eyes off the road to see what it is; my phone will whisper it into my ear.
