If my wife wants to buy an ipad II what does she need to do shopping for hours at a time on the internet while driving

Question

My wife wants to do internet searches and shop for hours on end while I'm driving.  What does she need if we get an Ipad 2?
Some people here at the office say I need Wi-Fi.  Some say 3G.  Some say I need to sign up with a carrier on some type of monthly plan to get the internet.
Help!!
I need this while we drive from state to state and not for getting on the internet through some hotel Wi-Fi Connection.
Thanks,

Answer 1

3G coverage and overall performance between Verizon and AT&T varies depending on where you are, and depending on where you are you may have no 3G service at all with any carrier.
The other consideration is the price-points of various data plans, they differ between size and cost.
But all plans are month-to-month, meaning that you can turn the service off anytime you want, and for as long as you want, but when you activate 3G service you pay for 30 days of service regardless if you turn 3G off (so turn it off on the 29th day if you won't need 3G next month).  You can do all of this right from the iPad, and you don't have to set anything up at the time of purchase (other than choose your carrier).  I bought a Verizon 3G iPad 6 weeks ago and have not yet activated 3G, but will do so soon while travelling.
