Sharp's latest high-res Windows tablet is an Ultrabook minus the keyboard

Let's see: sporty Intel Core i5 processor and Windows 8.1? Check. Retina-esque 3,200 x 1,800 15.6-inch display? Check. Plus 4GB RAM and a 128GB SSD? Of course. If Sharp's RW-16G sounds like the laptop of your dreams, sorry, but it's actually a tablet in the mold of Panasonic's 20-inch, 4K Toughpad or Samsung's new Galaxy Note Pro 12.2. Sharp is keying in on business users for the new slate with a bundled stylus for graphics pros, along with screen sharing to assist during presentations. With the Japanese company's own IGZO screen tech, it'll also outlast everyone's bladders with nine hours of battery life. There's no pricing or availability yet, but so far, it looks destined for the Japanese market only -- if you're stateside, Samsung's aforementioned model or a Surface Pro 2 might have to do.
