Mobility, not just speed, will be a key factor in winning over high-speed Internet customers, according to AT&T Inc. wireless chief Ralph de la Vega. The telecommunications giant on Wednesday introduced a $50 netbook that De la Vega said will play a key role in expanding the mobile capabilities of its consumers. He also hopes it will give AT&T an edge in its pitched battle with the cable providers in offering Internet, phone and television services. Cable companies such as Comcast Corp. have slammed the telecom companies and their DSL offering, which they claim is slower. De la Vega, however, believes that it's more important that AT&T can offer the same high-speed Internet experience found on the home PC on the road.
