The downside is that the V634 has a resolution of only 1366 x 768 pixels. The company does offer a more expensive V834 with 2560 x 1440 pixel resolution but that version has a battery life of "only" 14 hours.
Both versions offer Intel Core i5 CPUs with clock speeds ranging from 1.6GHz to 2.6GHz, along with 8GB RAM, a 128GB SSD, Bluetooth 4.0 and HDMI video out, including support for 4K output. You'll also get WiFi of course, with 802.11 a/b/g/n/ac support. The whole package weighs in at just 1.12kg, thanks to a 'honeycomb structure' and magnesium alloy construction.
Engadget reports that the V634 will launch in Japan tomorrow (although Engadget Japanese claims that the release date is Friday), with prices starting from ¥144,000 JPY ($1,440 USD / €1,070 EUR / £895 GBP). The higher-res V834 starts from ¥153,000 JPY ($1,530 USD / €1,130 EUR / £950 GBP). For now, it appears that the two Ultrabooks will be sold only in Japan.
