I use Siri many times a day, but some of her stupidity is really lame. When my phone is in airplane mode with wifi enabled, I can go to the phone app and place calls as it's supposed to do, but if I tell Siri to call someone she says "Hmm, it looks like your phone is in airplane mode..." and won't initiate any phone calls. So stupid. Sometimes Apple's left hand doesn't know what its right hand is doing. In iOS 8 Apple enabled wifi calling, and that's great! But apparently the people in charge of Siri never got the memo.
