One of the more annoying features of Optus' prepaid offering for mobile broadband is that it counts data in 10MB chunks, which means your usage can ratchet up fairly speedily. That will change from late April, with Optus switching to a slightly more reasonable per MB charging model.

After seeing mention of this on Twitter, we contacted Optus and it confirmed that the change is coming:
Effective 25th April 2012, Optus Prepaid Mobile Broadband will move from charging data at 10MB increments to 1MB increments meaning data will now be counted in smaller increments to ensure that customers are getting the best value from their service.
Contract customers still get counted per kilobyte, which is even better, but this is still a welcome improvement.
