Whoa, you're kidding me right? I know it's still available for existing customers. Thing is, that's a VERY small portion of long term iPad customers. 2gb a month will not cut it. This is a huge detriment to the iPad. Apple needs to cut them out ASAP. I can get past the service problems, taking on the iPhones sudden influx of traffic is more difficult than they think. Capping data at a measly TWO GB? That's absurd.
Video content is the primary culprit. A few episodes of any substantive-length video podcast pushes you over the cap before you even use your device for anything else. Take "This Week in Startups" for example. The last episode was 700mb. So 1:40 worth of video content would consume 35% of your available data.
The only thing I use my iPad for is watching TV shows and university lectures I downloaded from iTunes store. I'd be WAY over 2GB. Then again, I'm not sure if you can download this content over 3G as I don't have that model of the iPad.
