Ok so I am planning on getting the HTC Aria (AT&T) and i was gonna get the 200 mbs data plan, and i wanted to know if this is enough for what I want to do. I am not gonna check e-mail or go on facebook, i might go on twitter once a week. I am mainly going to download and use apps, and use the internet about 5 hours a month. 2nd question, does going on the android market and using apps use data? I have never owned an android, or even had a data plan before so i a noob at this.
