You are correct, that individual data usage must be considered when making a final decison. That is why in one of my earlier posts I said that for those people are not concerned about data use Etisalat's iPhone is a bad deal. That is because you can buy an iPhone for less that Plan #1 price and just pay as you go without using data.
However, for people who use data, iPhone plans are sweet. If they use more than what iPhone package provides, they can always subscribe to one of the data plans I mentined few posts above.
iPhone is limp and numb without internet connection. Most of it sweet features and programs loose their functionality. GPS, instant messaging and Facebooking, hehe.
I can't tell how much data an average person uses. It will vary too greatly to be able to come up with an average. It highly depends on things you like to do. You can, however, test and see what kind of Kbs you are pumping in yourself. In your iPhone's general settings there is a usage button. Simply reset it, connect to WiFi and play around with the phone. Load up few pages, check your facebook, message a few friends, upload a pic or two, send a few e-mails, check local movie listings and show times then go back to the usage and see how much you downloaded and uploaded.
Here is something else for you to think about...
If you are paying 2 fils per KB of data, 139AED is good enough for 6950KB. There are 1024KBs in 1MB, so 6950KB is a little under 7MB. To compare, you can just get 10MB generic data plan and pay 50AED.
Any way you look at it, its a good deal. We both want better and I am sure that sooner than later we will see it, but I am not going to hold my breath for it and enjoy this great offer right now.
