The main problem with using the N810 on the Internet is that it's only usable where wireless is available. But the N810 can easily be tethered to the Centro, so that the phone provides the connection to the Internet anywhere.

All you need is software called Usbmodem, and once you get it set up, it makes tethering just a button click away.

I'm amazed that your wife likes her Centro so much. I'm impatiently waiting for the chance to get rid of mine. The only thing that keeps me going is that am in the employee discount plan that only costs $30 a month (and which is not available for new customers).

I bought extra batteries for my Centro, which has awful battery life, which helps, once you learn the trick of opening and closing the Centro to access the battery, which is quite a tussle for the first few times.
