I know that 200MB is not much, but contracts with 1GB or more cost much more than those with only that small amount of traffic.
I could get a contract for 35€/month and get a 3GS for free with 200MB/month (after that only GPRS speed), plus a UMTS-Stick for my notebook with a flatrate.
A contract with 5GB/month would cost at least 400€ more in 2 years...
