TC Mag discovered a Chinese company has developed its own Eee Keyboard. The device is named Cross PC U510, it features a 5" touchscreen and is based on the NVIDIA ION platform. Inside the keyboard is the NVIDIA GeForce 9400 IGP, Intel Atom 1.6GHz processor, 2GB RAM and a 250GB HDD.
Unfortunately, there's no dual-display support so you can't use the 5" touchscreen in combination with a larger screen.
The Cross PC U510 has WiFi but no wireless HD support, it is powered by Windows XP, and is said to cost about $569. No word on international availability.
