Good summary of the predictions for 2009 on the Government Technology portal. The one I am most scared about will hopefully not come true:

“By the end of next year 2010, wireless operators will cease to offer unlimited (flat-rate) mobile data plans. Gartner warns that users must expect data throughput limitations on 3G to continue and plan mobile enterprise services accordingly. New bandwidth-intensive smart phones and mobile Internet devices are accelerating the demand for bandwidth, with devices like Apple's iPhone driving significant increases in mobile data usage. Networks are already hitting capacity and increased customer demand is impacting network availability and effective throughput. Mobile data services are already slowing down as carriers frequently fail to deliver on the promised speeds.”
