i guess im a power user whose outgrowing what they can offer and i dont use torrents via t-mo, if they offered unlimited unlimited data for $40-$50 i'd gladly stay & pay but they don't
tmo offers 5gb for $20-$30 advertised as unlimited data which is really unlimited limited data, i tried using pandora, youtube hd, audio galaxy, google voice, google maps & countless other apps on 2G which is the speeds you're throttled down to after going over 5gb & man I can only imagine video streaming via ustream or video chatting/calling which may be a focus on the next android os via 2G, plus everything's moving to the clouds
at&t is worst with its 2gb cap imo, so I plan on switching over to sprint or verizon, sprint & verizon doesn't have a cap on their unlimited plans, but they are about $10 more then t-mobile (samsung or motorola may be behind the next google experience phone, so i'm waiting for the CES or 1st half of next year to decide which one I'll be heading over to) also by then I'd be able to see will the two companies follow suit and add caps to their 4g networks
plus i plan on purchasing a wifi only tablet (to use with tethering), even tho a netflix or hulu app havent hit the android market yet i plan on using those services via flash the web browser, along with many other cool apps that may require data now that we've crossed the 100,000 mark
