When Yuta Moriya was offered Apple Inc.'s 613-gram iPad by his employer last summer, he envisioned a future free of lugging his laptop around for client visits. He was wrong.

"I used to have to carry my laptop, a charger and some brochures," said Moriya, 29, a used-car salesman at Tokyo-based Gulliver International Co. "After the iPad, I carried the iPad, a charger for the iPad, the laptop, the charger for the laptop and the brochures."

Salarymen like Moriya are reluctant to embrace iPad tablets, the fastest-growing segment in the computer industry, because they aren't light enough or functional enough to replace laptops in Japan.
