?s on google voice search from a former Evo user, current iphone user

Hi. had the Evo 4g and loved it. Well, I hated Sense and always monkeyed around with different OSes.

Anyhow, got the iphone 4s about a year ago... Like it for some things (mainly apps are better)..

For those that don't know, google recently released a voice search app for the iphone and it is amazing. I know it is built into the latest Android OS, so I am preaching to the choir here

Question: how integrated is google search with Android now?

1) can it open apps

2) can it play a song or playlist

3) can it send a text?

I am considering going back to Android.. I hate Siri and think Android innovates more/better
