Totally worthless deal for 99.99% of the public unless it has tethering included free of charge which would likely prompt me to sign up.
Not really, I personally use roughly 2 gb of data each month, without tethering, and I love the fact that I dont have to watch my data usage at the end of the month to make sure I dont get slap with huge fees. For many of us who stream music or surf the web anytime we are out and bored, its worth paying the extra 5 bucks a month and having the piece of mind that we wont be racking up fees if we accidentally go over.
