Speaking as someone who currently has a 3G data line for my iPad 2 I can tell you that your best bet is to really look into why you want a data connection for your iPad. Personally, I got it so that I can check email and have access to browse the web and read the news without having to haul around a MIFI device in addition to my iPad. For any heavy data consumption, you will still want to be connected to a WIFI network though. I really think it comes down to how much you plan to use it and how often you are away from WIFI access. For me this time is actually quite little since I have WIFI at work and home, so I am only really consuming my 3G data a small percentage of the day. I will note that I have not come even remotely close to my 2GB cap on either my iPhone or iPad. Apple does a good job protecting you from yourself on a lot of things too regarding large app downloads being denied unless you are connected to a WIFI network.

I wouldn't worry about the 4G at all. The faster speeds wont magically make you use more data. It will just be giving the same amount of data, faster.
Also, there is no video you will be streaming that can take advantage of the screen anyway. Any streaming site will only be streaming at 1080p, and most mobile sites dont stream at that resolution. In addition, there are no consumer video electronics that can meet the resolution of the screen of the iPad.

Lack of Unlimited Data is a problem, a problem that harkens back to scaled dialup plans in the 90s. It's something else to worry about. I agree that that's one of the overlooked problems by many consumers. Youtube, Hulu and Netflix all have great potential to max that data throughput as well, especially if each service takes the initiative to autoscale the resolution of video (I.E. Youtube decides to stream in 720p based off of your 4G LTE connection).

My only recommendation would be to get a data managing app that alerts you when you are about up on the data. Also, planning out data usage is a good idea too. Base it on your work schedule, school schedule, planned downtime, etc.

Hopefully in the coming years, tower capacity will catch up with user demand and allow unlimited data to come back to the forefront. I also hope with said hardware improvement, consumers win out over capital greed. Try to picture a much larger amount of spectrum available still tiered into buckets of data allowed per month. Great for the Wireless company, terrible for the consumer.

On the Gilmore Gang this past week, Scoble was using his iPad's 4G connection to provide his internet for his Mac and Skype call and he used 2GB in about an hour. He had to go and purchase more data mid show. Data caps suck and they don't even remotely solve the problems that the carriers would have you believe they are capping them for.

With 4-g technology we can download as many data we want ,but there is free download service is available when we subscribe new 4-g service. Note that the free downloading has a limit and if we download more data, then it will cost as per your subscription.
