One of the hottest topics at CTIA last week wasn’t much of a mobile device at all. But a tremendous amount of attention was focused on netbooks, the mini-laptops that allow users to surf the Internet, email and manage digital files, including photos and music. For handset makers, it represents a new form factor that can attract a wider customer base, and for operators it provides the opportunity to sell more high-priced wireless data plans for those seeking to be always connected.

Last week, AT&T was the first U.S. carrier to announce that it was launching a netbook trial in Atlanta and Philadelphia, where residents could buy one for as little as $50 with the purchase of an AT&T (NYSE: T) wireless data plan and wired DSL plan. For those not interested in DSL, the laptops would cost between $100 and $350. Wireless plans range between $40 and $60 a month. Without those services, typically cost between $450 and $600. Last month, it was rumored that Verizon Wireless will begin selling subsidized netbooks as early as next quarter, but no plans have officially been announced.
