Except.... you can't do it from a sleeping phone, you have to unlock, then press the home to get to google now, THEN press the mic button to get it to listen to you, then HOPE it gets your request right. The first few times I tried to do it, it googled wrong things, rather than dialing.
Seriously, this plus the *huge* learning curve, my magically disappearing calendar appointments, the charging issues/battery life problems, the volume button, lack of a silence button/switch that will quiet ALL noises... I'm starting to rethink this.
I like to carry ONE device. Not two, three, or four. At the moment, I'm having to still carry around my 4s for the calendar, the ipod and apps I haven't found replacements for yet. Maybe I'm jaded because I'm expecting to be as blown away as I was when I got my 3gs. Or at least as pleased as I was when I got my 4s. I am having to hunt for things that I like about the phone and so far, the inconveniences are overshadowing the good points-- this is shocking to me, because i was seriously HYPED about this phone.
