Pre-paid or Post-paid - which one is better? - off topic, but again - a penny saved is a penny earned and then a penny invested

Now on a slightly different topic - pre-paid vs post-paid mobile service. What do you think is beneficial for anybody who makes any amount of call? My research suggested - pre-paid is any time better for both frequent and less frequent callesrs and both STD and local callers. Compare this:

1. Minimum post paid rental for Airtel is Rs 249 which is for having the service calling others at a discounted rate of Rs.50 and STD @ Rs.1.50. On top of that there is a 12% (some decimals missed) tax on the total bill.

2. Pre-paid - Recharge for Rs 1111 and get Rs. 1250 worth of talk time (for lifetime custmers this is valid for lifetime). Then recharge Rs. 94 to get Rs. 1 STD (present in post-paid also) and Rs..60 M-M calls. So effectively you are getting full talk time and Airtel pays you rent of Rs. 45..:)

This is just an illustration and then both have their good and bad points - like post paid can enjoy GPRS 100 MB plan, pre-paid customers have to go for unlimited one etc.. Your comments are welcome.

FYI I am still a post-paid customer..:)
