Thanks for pointing out some places where my article may have been misunderstood. I agree with you that there is definitely overhead for box.net to be providing the 50GB free for new users and I will re-iterate my point that I definitely believe that they will eventually profit from the risk they took. The point I was trying to make was less on the price but more on the rate at which the web is expanding in the sense of space and what we set as limits and caps.
Comparing how things were less than a decade about and now (with web hosting plans, gmail's release) suggests a growing trend that the web is quickly becoming "unlimited", and this sense of "unlimited" is quickly becoming the norm. The gripe I was trying to express with the article was how some companies fail to see that by continuing to quantify the resources available to users.
