Best Buy is offering under their Escape online shop a couple of UMPCs and notebooks which are Japanese market only. They offer these through a partnership with the pioneering Japanese notebook exporter Dynamism.

Dynamism is in the business since 1997, and we worked with them in the past on a couple of product reviews. They are a great company to work with. Looking at the current limited offering in the Best Buy Escape shop, you also can just go directly to Dynamism and order there. Pricing is the same. The partnership is good marketing for Dynamism and should help them spread the word.

Dynamism says that there will be more products in the Escape shop in the near future.

Asus Ultra Mobile PC with Intel® Celeron® M Processor ULV
Raon Ultra Mobile PC with AMD Geode™ Processor LX800
