Toshiba several times has increased production of its Portege 3500 tablet, after having trouble meeting initial demand, said Mark Simons, vice president of Toshiba's transactional business group.
Meanwhile, HP's "tablet sales have been exceeding expectations from the day we launched," said Ted Clark, a vice president for HP's personal systems group.
Tablet PCs are still a fairly small segment of the overall notebook market. But the devices have so far been a bright spot for manufacturers which are still feeling the effects of the PC market crash of 2001. The smaller machines have generated interest among the legal, real estate and health care industries, as well as from some consumers, executives from Toshiba and HP said.
