22 and 0 issues with sync. Voice recognition for me works 95+% of the time. Sure you have to make sure you speak somewhat clearly, but voice rec will always be like that to a certain extent.
One thing to note regarding playing artists/songs via voice, that most people don't seem to know about when I ask them:
The voice command is based on the mp3's ID3 meta data, it doesn't necessarily matter if it comes up on your phone as a particular artist or song name, if the ID3 tags are not set correctly, voice recognition will not work. This mostly affects people that obtain their music.....illegitimately. If you purchase it through itunes/amazon the ID3 tags come preset correctly. If you open the song in a program like iTunes you can edit the metadata.
Also, applink with pandora is fantastic and works flawlessly.
Also, those saying age doesn't have any relation to computer literacy, don't be ridiculous. It may not have a direct relation to computer literacy, but the simple fact that the younger generations have grown up constantly using similar systems simply makes it easier for them to interact with newer technology. I know several older men and women who are very good with computers/tech, but they are definitely the minority.
