Panasonic’s Let’s Note (aka Toughbook) series is the favorite choice among many Japanese hackers. And today the company announced [JP] two new notebooks from the series with Windows 7 on board. Panasonic says their 16 hours of battery life is unmatched in the industry.

The so-called N8 and S8 are the models Panasonic will market in Japan as “winter season computers”. The S8 has an internal super-multi drive, but otherwise the main specs are identical for both Toughbooks: Intel Core 2 Duo P8700 processor (2.53GHz), 250GB HDD, 12.1-inch WXGA LCD, 2GB RAM (max: 4GB RAM), Wi-Fi, WiMax, one SD slot, one HDMI interface and three USB 2.0 ports.

The S8 and N8 will go on sale in Japan on October 22 (prices: $2,400 for the S8 and $2,300 for the N8). No word yet on international sales plans from Panasonic.
