Microsoft introduced the Surface Pro 3 tablet on Tuesday. It’s actually a tablet and laptop in one with multiple processor, RAM and storage options. For those of you who like it thin, it’s 30% thinner than an 11-inch MacBook Air. It also happens to be the company’s biggest tablet to date.

The Surface Pro 3 has a 12-inch ClearType Full HD display, and a new Surface Pen, which has been completely redesigned.

It has 4th-generation Intel Core processor options, click-in keyboards, and a multiposition kickstand. It runs Windows 8.1 Pro. Speakers have Dolby Audio enhanced sound.Battery life lasts up to nine hours.

There’s a new type cover, a full-size USB 3.0 port, microSD card reader and Mini DisplayPort, and optional accessories like a new docking station and ethernet adapter.

“So many people carry both a laptop and a tablet but really want just one device that serves all purposes,” said Panos Panay, corporate vice president of Microsoft Surface. “Surface Pro 3 is the tablet that can replace your laptop — packing all the performance of a fully powered laptop into a thin, light and beautifully designed device. You’ll love being able to carry a single device for your next class, workday or weekend getaway knowing you have all the power you need.”

“Our customers know that every Surface we’ve shipped was built to do more than other tablets, and how they use Surface validates that a tablet can be a great tool for productivity,” he said. “Yet many people aren’t ready to give up their laptops for tablets, and most people still carry both. When walking into a store, they feel they have to decide between a tablet for portability and entertainment or a laptop to really get things done. For the most part, tablets have been designed to be great for watching movies, reading books, playing games, browsing the web, and amazing for digital “snacking” with apps. Most laptops are designed to help you type term papers, write letters, work on big applications, work on spreadsheets, browse the web, create content, make movies… you name it. In designing Surface, we wanted to design a device that can marry the power of the full PC without compromising the sleek finish, elegant look and feel, light weight, thinness, and great battery life that we expect from a tablet.”
