Samsung Electronics is planning to put its Q1 ultra mobile PC on sale world-wide in May.

Based on Microsoft and Intel's ultra-mobile Origami platform, the Q1 was one of the stars of the Cebit trade show in Germany last month, where it and the Origami platform were unveiled (read our Q1 review, and our analysis of Origami's prospects).

The Q1 will be available first in Samsung's home market of South Korea, from May 1, and will cost 1,199,000 won ($1,264 or €1,043), said Anthony Lee, a spokesman for Samsung in Seoul. That's roughly in line with the €1,000 price tag that Samsung quoted at Cebit and above Microsoft's predicted $500 to $1,000 price range for ultra mobile PCs.

It will go on sale later in May, in the US, Europe and China at prices yet to be announced, said Lee.

Samsung hopes to sell around 100,000 units of the Q1 in South Korea within its first 12 months on sale and for overseas sales to total 300,000 units over the same period.

Origami machines run a tablet version of the Windows XP operating system and are intended to fit in the market between laptop PCs and PDAs (personal digital assistants). Samsung's Q1, for example, has a 7-inch LCD (liquid crystal display) monitor, is about half the size of an average laptop PC, and weighs less. It measures 22.7 centimeters by 13.9 cm by 2.6 cm and weighs 779 grams.

Other specifications are slightly below those of a typical laptop PC. The Q1 is based on an Intel Celeron M processor running at 900MHz. It has 512 Mbyte of memory and a 40 Gbyte, hard disk drive. There is a wired and wireless LAN adapter, Bluetooth and a Compact Flash card slot that could be used for other types of modem.

While Origami clearly is potentially exciting, there seem to be differences between the Microsoft and Intel versions of the concept and other pitfalls awaiting it.
