They might be obsolete in the future if other companies start to offer unlimited for a cheaper price, such as cricket or some other company in the future.
Also there is a small chance that the plan might get canceled by att in the future.
Besides these yeah i guess your correct, but you would just have to put in a little work.
Dont think many people would buy it for 150, wouldnt they just rather get one themselves?
I doubt it will ever become obsolete... its the ONLY un-throttled, un-monitored UDP on the market, probably the only one ever existed.
the general trends of carriers are moving away from unlimited data.
yes, Tmobile has some 'unlimited' data, but is it really 'unlimited'? it's no where close to this plan.
and I also doubt att will ever cancel this plan. some reasons
1. the plan was introduced by apple. there's 'apple factor' in it... plus those customers who bought iPad so soon after it was released, are more likely to be high-paying high value customers, att don't want to loose them
2. the total amount of plan sold on this isn't that huge, it will not cause a huge impact on ATT's network, so they just in general don't care.
3. grandfathering is like a common practice in the industry, canceling a plan, especially an unlimited data plan, causes bad PR.
