The three devices and specs are:
1) 8″ 1280 x 800 screen, Intel Bay Trail CPU, 8 hours battery life, 2 GB RAM, 32 GB SSD. Office Home and Student 2013 will be bundled. This is the one that was seen at IDF in San Francisco.
2) 10.8″ 1920 x 1080 screen, ARM Qualcomm CPU, 10 hours battery life, 2 GB RAM, 32 GB SSD. Office Home and Student 2013 will be bundled.
3) 10.8″ 1920 x 1080 screen, Intel Bay Trail CPU, 10 hours battery life, 2 GB RAM, 64 GB SSD, 4G / LTE built-in.
The documentation seen by GNC suggests that the devices will be running Windows 8.1 out of the box but it’s not totally clear. There’s also no information on pricing or availability so we’ll just have to wait until next week for the press conference to learn more.
