Road warriors looking for the most PC in the smallest package will probably not have to look any further than Fujitsu's U810. It is quite possibly the most feature-complete Ultra Mobile PC (UMPC) I have ever seen. In fact, it probably shouldn't even be called a UMPC since it's a convertible that switches between a traditional notebook mode and a tablet mode. Call it an Ultra Mobile Tablet, or UMT.

As Fujitsu's senior director of mobile product marketing Paul Moore rattled off what's included in the tiny PC, I started to wonder what's not in the PC, which retails for $999.

• 800-Mhz Intel A110 Processor (Intel's UMPC processor)
• Fingerprint-based biometrics
• Trusted Platform Module
• Touch screen (for tablet functionality)
• Integrated HSUPA networking (HSUPA is the high-speed uplink cousin to HSDPA)
• Wi-Fi and hard-wired Ethernet
• Bluetooth
• Keyboard illuminators for working in the dark
• USB ports
• Compact Flash slot
• SD slot
• Optional docking station for external monitor and keyboard connectivity
• Built-in Webcam
• 40-Gbyte hard drive
• 1-Gbyte RAM

As you can see in the video, using its qwerty keyboard is probably going to be an exercise in touch-typing for people with small fingers, but one of thumb-typing for those of us with big fingers. The keyboard is just big enough that it could be a bit of an stretch for many people to reach the middle keys with their thumbs while gripping the UMPC from its edges.

For road warriors or mobile business applications (because of the Trusted Platform Module and fingerprint reader) where a smartphone doesn't quite get the job done (either too small or a full-blown version of Windows is required) and most notebooks are too much to carry, Fujitsu has packed some incredible punch into a tight space.
