...days, late 90's. We used RACKSHACK for our cloud. We got an allotment of transfer included with the rental, and paid "Per G" for going over.
As time went by, the allocation became larger, and so the cost per GB was lower. The speed was as fast as a 100baseT card (and your server) could pump out.
So we got "Unlimited Speed" for measured data. In terms of having happy hosting customers, it was the best buy for me at the time.
We have since changed data centers and have a smaller amout of bandwidth, but no cap on data transfer.
In both instances, the price was clearly stated, and i chose the best fit for my needs.
As alex hyperbolicly states, your use of the Queen's English in 36 point Helvetica implies a contract that can't be negated in 6 point comic sans. There is nothing "wrong" with a moon landing simulator ride, nor is measured data unreasonable at this early stage of cheap wireless transmission. But in both cases the advertising needs to clearly state the costs and benefits of a particular product.
With the provisioning of 4G, and aggressive pricing by Sprint partner CLEAR, unmeasured data will compete with measured transfer. This will not happen soon, it is happening already. It would be very interesting to see data sales stats in CLEAR cities.
Hopefully, price pressure from 4G will force the greedy carriers (tm) to create more reasonable Per GB pricing for tethering and the new hotspot phones.
