The Panasonic 4K tablet, which runs on Windows 8, was unveiled alongside a 4K OLED TV, and is aimed squarely professionals such as photographers and architects. While it may be out of reach for most of us mere mortals, it's still an interesting piece of kit - here's what we thought...
Panasonic 4K tablet: Size and build
The tablet is a chunky beast, so it's not something you're likely to be casually chucking into your man bag too often. The metallic back panel gives the tablet a premium finish, while the white plastic bezel on the front gives it the look of a giant iPad.
Panasonic 4K tablet: Features
The tablet packs an Intel Core i5 3427U vPro processor, clocking in at a speedy 1.8GHz, and you'll also get the benefit of an Nvidia GeForce graphics processor.
Panasonic 4K tablet: Screen
The massive 20-inch screen is LED backlit, so it's nice and bright and colours pop out, which is obviously good news for the design pros and shutterbugs. The 3840x2560-pixel resolution means that photos are packed with detail, even when zooming in.
Panasonic 4K tablet: Verdict
The Panasonic 4K tablet is a stunning piece of kit, but it's likely to have a very niche market. May design pros who need a big high-res screen will likely 'make do' with the infinitely more portable 15-inch MacBook Pro Retina. For those on photo shoots, or maybe architects showing off floor plans it may well be a useful tool, but it's not likely to come cheap.
Panasonic is remaining tight-lipped when pushed on the subject of price, but it's going to be the most expensive tablet around when it finally appears (assuming that nothing similar surfaces in the meantime). Hopefully we'll manage to get our mitts on one again later in the year...
