I didn't see anything wrong with the old system. I got some pretty big ETC's for relatively low inconvenience. I've never gotten one of those calls 24/48hrs ahead to make a change, but being able to talk to someone and negotiate is a big plus. After the "dao-incident" I fear the days of making a quick buck are coming to an end.
I'm pretty skeptical about this approach and the accuracy of the article. Devil's in the details. While it would be nice to possibly be able to make a change before going to the airport (so I spend my time at home versus at the airport), this automated system takes away perks that you might get at the airport (F upgrade, higher ETC, change dates, airport, meal vouchers, knowing exactly what you're getting).
