It's called the Nokia Booklet 3G, and the first thing that stood out to me is the aluminium enclosure, and it looks like Nokia has taken a few cues from Apple on this one. Still, the device has its own look and does - if that's even possible - look like a Nokia product. It's only 2cm thin and weighs 1.25kg.
Since this is Nokia we're talking about, the Booklet comes with 3G/HSPA built-in, and there's room for a hot-swappable SIM card. The promised battery life is nothing short of amazing: up to 12 hours, Nokia claims. How, exactly, the company achieves such battery life is a mystery - common Atom-based netbooks can barely squeeze out 2.5-3 hours on a 3 cell battery, and maybe 4-5 hours on a 6 cell battery.
The display is a 10.1" glass-covered one, with a HD ready resolution - which probably means 1280x800. It also comes with an HDMI-out so you can connect it to your HDTV if needed. Since the regular Atom platform can't handle HD content, the Booklet is either based on NVIDIA's Ion platform, or it has a specific HD accelerator chip.
