The Nav7 doesn't can come with without any operating system, but if you want to pay a bit more for one, it'll come with 32-bit Windows 7, in any one of the versions. It comes standard with a 1.6GHz Intel Atom Z530, a 16GB SSD, and 1GB of DDR2 RAM. You can definitely upgrade those standards, though, with options for 32GB or 64GB SSDs and up to 2GB of DDR2 RAM.
Other things that are included are a 1024 x 600 7-inch capacitive screen, a 1.3MP front-facing camera, two USB 2.0 ports, 802.11n wireless networking, audio in/out, two integrated speakers, and an integrated touchpad on the back with dedicated mouse buttons.
You can buy the barebones unit without any OS for $599, but with options and software, you can run the Nav7 up through the $1000 mark. Take a look after the break at some press pictures.
