Dear Sir. I am a graduate student in Accounting. Generally I use Computer internet. most of the time I need to calculate many complex calculation for my regular study. So I need to use Calculator, Converter & world clock. therefor I need these 3 item in a way. One of my friend told me to use the Gboxapp, but I did not agree with him. I want to use any one of them: google, yahoo, babylon or Gboxapp. He also suggest me to search in the google by typing "gboxapp" to know more about the toolbar reputation. he also gave me the Url: http://appgbox..in/ Suggest me please, which one should I use?
