Handspring will take the wraps off two new devices in Tokyo on Monday.

Jeff Hawkins, co-founder of Handspring and one of the founders of Palm Computing, will be on hand along with Shigeki Komiyama, general manager of the company's Japanese affiliate Handspring Japan KK, to present the new computers.

In Japan, the market for PDA’s is becoming saturated, with Sony being the latest entrant into the market. Sony launched its first PDA - based on the Palm OS - in August. The Clie comes in both monochrome and colour versions in Japan, although monochrome only elsewhere, and is being sold as an accessory for the audio-visual or entertainment-conscious consumer - a market segment so far largely ignored by Handspring or Palm.

Other competition is also on the horizon, from Sharp, Sanyo and UK-firm, Symbian.
