After months of teasing, Plastic Logic finally unveiled its vaunted Que proReader. It’s not strictly speaking an e-book reader, although it is. With a large-format 10.7-inch diagonal touchscreen, Que is designed for the business user. It displays Microsoft Office documents, PDF files, magazines and newspapers, maintaining their font/layout look-and-feel. The idea is you can leave that pile of papers in the office while you’re traveling. You can also write notes right on a document, which you can then share with co-workers.

Que is available in two flavors, a 4GB model that’ll hold 35,000 documents ($650), and an 8GB version with Wi-Fi and an AT&T 3G connection to Barnes & Noble and will store 75,000 documents ($800). Both will be available in mid-April at B&N stores and online, but can be pre-ordered now from the Que site.

How the Que works — and how it compares to the Kindle — after the jump.
