Well. for me it's like saving money... anything I don't need I can save and buy something big someday... for data it's much the same, Maybe I only use 1GB per month of my 4GB data cap but it would be nice to be able to roll that over for up 2 a year then maybe I'll go on holiday where there's no wifi and I can tether my ipad to my phone and watch netflicks etc.. I think there must be a lot of money to be lost in having this and that's why they are so anti roll over.
