Summary: Device requires driver and the website listed in the product's user guide is not operational. HP's standard website only provides a copy of the useless manual.
Summary: The calculator works as a calculator, but so do the ones you can buy at the Dollar Store. The Hewlett-Packard keypad does not work with my Vista platform on my computer.
Summary: I am impressed with the HP CalcPad 200. The 3 way power makes this calculator useful at the desktop, laptop or any where you would like without a computer.
Summary: I like it it helps with my accounting class, either as a stand alone calculator or on the days that I need my lap top plug it in and use it as both calculator and data
Summary: works just as expected!I've even taken it in my purse for when I'm going to clients, the back up batteries that comes with gives you that freedom!
