I think wifi is very useful as if yuo have wifi at home and your mobile phone also supports wifi it bvecomes great. You do not need to be in front of you PC everytime to use the net you can use the net from your mobile itself. You can surf easily. And if ever two persons want to use the net at the same time there is no need to worry as one can use the net on the PC and the other from the mobile phone. Share your views.
