Fanboys have been running Ubuntu on Sharp's deceased Zaurus lineup of PDAs for years. Now Sharp makes it official with the launch of this 5-inch, 1024 x600 TFT LCD touchscreen NetWalker smartbook, aka the PC-Z1. It's not a Zaurus per se, but the compact 161.4 x 108.7 x 19.7 ~ 24.8mm / 409g device certainly resurrects its ghost. Underpinning the device is an 800MHz Freescale i.MX515 CPU built around the ARM Cortex-A8 architecture, 512MB of memory, 4GB of on-board flash storage (with microSDHC expansion for another 16GB), 802.11b/g WiFi, 2x USB, and QWERTY keyboard going 68 percent of full-size. Sorry, no 3G data. The PC-Z1 features a 3-second quick launch, non-removable 10-hour battery, and is purposely positioned by Sharp as a taint -- it ain't quite a smartphone and 't ain't quite a laptop. Good luck with that Sharp. The device is expected to hit Japan on September 25th for ¥44,800. That's about $479 whenever it might come Stateside.It's worth noting that the current US ban on the import of BGA-packaged products like Freescale's i.MX processors should not affect the import of the PC-Z1 as Akihabara News contends. As we understand it, that ban affects the import of the chips, not the systems using them and assembled elsewhere. Otherwise, Amazon wouldn't be selling its Kindle , dig?[Via Akihabara News and Engadget Japanese Read [warning: Japanese PDF]
