Tethering was cool idea in the past, when wifi was not so readily available everywhere. I got 8 mbps wifi at home and work. There are plenty of hotspots like mcdonalds, starbucks, chickfila, malls. I think tethering may become a need in the future when there are 4g everywhere. The wifi in these hotspots are slow. Also, to tether, it will drain the phone battery and you reducing the bandwidth, too. However, if 4g is around, it may not reduce much bandwidth in sharing. Plus, the cap in the bandwidth from ATT gives another reason why tethering is pointless. There are androids phone that can tether, but that is just a marketing tool. Tethering is just not a need when wifi is plenty. Tethering is become cool in 2 to 3 years when hotspots are slow and 4g is faster. Do you think tethering is a need?
