Sharp has just announced what is being described as the first computer that will hit the market using Intel’s new low-voltage, high-power Atom processor. The Sharp D4 will be out in Japan in June for ¥39,800 or about $395 US. But there’s a catch. Users will also have to purchase a 2-year data plan for ¥2,100 per month, more than doubling the price. Engadget reports you can also pick up a D4 with no data plan, but it will set you back ¥128,600 or about $1250 US.

Still, the D4 looks pretty sweet:

• 1.33GHz Atom processor
• 5 inch 1024 x 600 pixel display
• 1GB RAM
• 40GB hard drive
• 2 MP camera
• 64-key slide-out keyboard
• WiFi and Bluetooth
• Windows Vista Home Premium and Microsoft Office Personal 2007
• Dimensions: 192 mm x 26 mm
• Weight: 470 grams
• Optional Bluetooth phone handset
• Optional GPS receiver

While the Sharp D4 is the first Atom-based computer to get a release date, it certainly won’t be the last. Intel officials say 20 more devices will be ready to ship soon.
