I have had a BlackBerry Curve 8900 for about a year without data and just put on the $15 200Mb plan because it was cheap enough. I knew 200Mb was enough on the BB because their push email didn't require much background data usage. After seeing how horrible the BB did on working with my GMail account, I have leaned towards getting an Android. My question is.. is the $15 plan going to provide enough data for me to use the Android? These are the things I plan on using with an Android: GMail sync, college email sync, Google Calendar sync, Google Contacts sync, and everything else, such as surfing the web, through WiFi (which shouldn't affect data usage). I don't know how well Android works with WiFi but I know BB can restrict its browser to only WiFi.
