Carl Bialik from WSJ writes "Palm ramped up its marketing campaign for its Treo smartphone while rival Research in Motion was embroiled in a patent fight, the Wall Street Journal reports. 'The result: at least 1,500 new inquiries about the Treo in the past few months from corporate customers, resulting in 600 free trials, Palm says. In total, Palm says it has more than doubled its number of sales leads since October. "The doors have been opening," says Ed Colligan, Palm's chief executive. At a November staff meeting, Mr. Colligan says he told his staff to "step things up. We have to go back and knock on doors and respond as fast as we can." ... Internally, Palm executives say they believe that the Treo will outsell BlackBerrys by the end of this year.'"
