When Apple first released Siri i have to say...it kind of sucked.
Siri never understood half the stuff you were saying and she made more mistakes than getting it right.
But, when IOS6 came out Siri was the biggest upgrade. I use Siri all the time to write texts and emails and while Siri isn't perfect, it is soooo much better than before.
Siri can do a bunch of things and it seems like everyday I find something new I can do with Siri. The latest thing I found Siri can do is really cool.
