AT&T Intros 100MB plan for the price of "unlimited"

According to the link in the title of this post, AT&T is replacing their "unlimited" $20 per month prepaid internet plan (which they discontinued a few months ago) with a 100MB plan. Also, no more $10 plan...it's $5 for 1 MB or $20 for 100. 1MB is hardly enough for anything...and 100MB is not enough if you're using a smartphone for more than light activity. Plus, no more $20 aircards. Ah well, c'est la vie when it comes to telecom advancements as dictated by telcos.
