South Korea's G.Mate has confirmed plans to sell Yopy, a Linux-based PDA (personal digital assistant), in late December via its website.

The company has begun accepting online orders for its £275 device, which is due for launch on 21 December.

The Yopy was first shown in public more than a year and a half ago, at the CeBit 2000 trade show in Hanover, Germany. Since then, the launch date has been postponed several times.

Its most recent appearance, at November's Comdex trade show in Las Vegas, revealed a drastic redesign to the Yopy. The PDA now sports a clamshell design, similar to many mobile phone handsets, rather than the more traditional PDA form factor.

Based around an Intel StrongARM processor, the Yopy runs the ARM Linux operating system and Windows X - a graphical user interface and messaging framework that runs on Unix workstations.

It has a 3.5in reflective LCD screen and a 240x320-pixel screen, along with 64MB of memory, a 40-button keypad, infrared and RS-232C serial ports.

It measures 102x69x15mm and weighs 140 grams. Battery life exceeds 12 hours according to G.Mate.
