At an event in Shanghai earlier today, Microsoft officially unveiled the all-new Surface Pro. The launch comes five days after we gave readers an exclusive first glimpse of the refreshed Windows 10-powered tablet.

A “refresh” is actually something of an understatement. Compared to the previous version of the device — the Surface Pro 4, which launched back in late 2015 — Microsoft is touting 13.5 hours battery life for the new Surface Pro, or 50 percent more than its predecessor. And it also comes with LTE built in.

There are also several versions of the device, each containing different Intel Core processors. While the Core m3 versions is fanless (and thus quiet), the faster i5 is also fanless — a rare beast — and Microsoft noted that although the i7 version isn’t fanless, it’s so quiet it “can’t be heard.”

At 8.5mm thick, with a 12.3-inch screen and starting at 1.69 pounds (0.77 kg), the new Surface Pro is comparable to the Surface Pro 4. But it packs LTE Advanced connectivity from the get-go, which should enhance its appeal to travelers who like built-in internet in their devices.

The new Surface Pro is available to preorder today, starting at $799 for the Intel Core m3, which has a 128GB SSD and 4GM of RAM. The various prices — depending on processor, RAM, and storage capacity — then range from $999 to $1,299, $1,599, $2,199, and $2,699. The most expensive version offers a Core i7 processor, 1TB hard drive, and 16GB of RAM
