Manufacturers admit to Ultra Mobile PC problems

The UMPC, as specified by Microsoft, is a flat, handheld device midway in size between a smartphone or PDA and a notebook PC. It has a touch-sensitive screen, but no keyboard.

Other standard features include a version of Windows XP Tablet PC Edition, Bluetooth, an internal hard drive, and a wireless internet connection.

Criticism of early UMPCs has focused on high prices, poor battery life, and excessive weight and heat. The same criticisms have bedevilled past attempts at similar handheld PC concepts.

An AMtek representative, who did not wish to be named, conceded that manufacturers are concerned.

A major problem is that users are comparing UMPCs with what seems to them the most similar existing product, the notebook PC.
