Siri works perfectly for me and has done since I got my iPhone 4S. Never had any problems at all, and it always understands me perfectly
Ha Ha! I have a mild Philadelphia accent and SIRI struggles with that.
I guess you guys have understandable accents. Us from PHI, NY, NJ, & BOS are struggling wit Siri. Lol
If you have nothing to compare it to, then I suppose siri is fantastic. If you want to use it for more than scheduling an appointment and a few simple facts, then it's quite useless and behind google.
I haven't used Google Now, but if it's anything like the Google app, then it's not that good. What are the differences?
By the way, Siri's dictation service is really good. Spot on for the most part.
