Closingracer,
To each his own. I have to use it pretty much everyday. Very useful feature to have then not to have.
Especially, when I am driving on the mainland using my gps and having to take or making a phone call.
Or I could be shopping on Amazon(who doesn't) while having a conversation with my wife and directing her or(vise versa) to a specific item we are interested in purchasing. Or looking at and discussing a certain online bills and or even account transactions at the same time. Or I could get a call from a friend to check out a certain website or Facebook post while putting them on speaker to continue our conversation.
With that said... I pretty much eliminated the need to say, ok... I'll have to call you back after I check it out? or having to call back multiple times to confirm or to re-confim anything I can check out while being online.
