Any transfer of graphics - playing Farmville on a PC is going to run through a lot of data and you are seeing that first hand. !0Gb is a lot to go through in two days - and expensive. A PC browser is also using more data when browsing a website than a mobile browser uses on the same webpages. Your wife would do better using a tablet or cell phone to play Farmville. Your message boards use a minimal amount of data and have no dent in that 10Gb used. Try to get the wife to slow down on her Farmville habit. There are a lot more constructive things to do on the Internet- and if she is playing this much it is a habit - and an expensive one!
