Bad news for “unlimited” data users, AT&T is killing off “unlimited”…again. This time, it’s hitting your household instead of your cellphone. According to reports from DSLReports and confirmation with AT&T PR guy, Seth Bloom, “unlimited” is a thing of the past. Starting May 2nd, your typical non-U-Verse package will have a 150GB data cap. U-Verse customers will have a bit loftier ceiling at 250GB. Overages will set you back $10 per extra 50GB of data. In a small act of good will, AT&T will email customers when they’ve hit 65%, 90%, and 100% of their allotted bandwidth.

AT&T maintains that a paltry 2% of customers (whom consume 20% of the company’s bandwidth) will be affected. That leaves 98% of us to go on with business as usual. However, we can’t but help but feel screwed by AT&T yet again. Comcast has a similar cap set around 250GB for all users regardless of package they subscribe to. With all media providers, ISPs, and every company in between talking up social networking, photo sharing, video uploads, and online gaming, 150GB is going to become less and less generous with each passing year. (Read: today’s heavy user is tomorrow’s standard user.) The most popular online service that could easily bump up against that cap that we can think of off hand — Netflix. AT&T should have led in this regard instead of merely following — half-assed we might add. But that’s business (and AT&T) for you.

We’d like to reach out to AT&T to provide us with some actual data proving to us that the killing of unlimited data is actually justified and that rising bandwidth usage is indeed a problem. It’s only fair, right? AT&T, we’re waiting…
