correct. the data plan can be a stand-alone plan ($29.99 for unlimited)
if you have a t-mobile voice plan, the unlimited data plan is $19.99
if t-mobile has good coverage in your area, there is no doubt it's the way to go. having free tethering
is also a bonus especially when you travel a lot (like i do) and you dont always have access to wi-fi and you don't want to shell out money to have access to certain wi-fi networks in restaurants, hotels, etc (yup, some hotels charge for wireless these days believe it or not).
