How big is too big for a tablet? While most of the industry has converged around two sizes (one about 7 inches from corner to corner, the other roughly 10 inches across), Samsung apparently wants to push the boundaries. According to a report from SamMobile, the company is currently working on an Android tablet with an 18.4-inch display. The device is reportedly codenamed "Tahoe," and although there are no details about when it might be unveiled, SamMobile claims it runs Android 5.1 Lollipop and features a TFT LCD display with a 1920 x 1080 resolution, a 1.6 GHz processor, 2GB of RAM, 32GB of internal storage, and rear and front cameras — 8 megapixels and 2.1 megapixels, respectively.

An 18.4-inch display would be too big for most users, but might suit specialized tasks

A tablet with an 18.4-inch display isn't unheard of, but if Samsung really is building such a device it's unlikely to be targeted at mainstream users. Panasonic's 20-inch ruggedized Toughpad, for example, would be too big for most users, but the company instead markets it as a tool for people who need large displays on the move, such as salespeople making a presentation, or architects visiting a build site. A big tablet from Samsung might fall into this professional devices category as well, although the choice of Android instead of Windows suggests more of an entertainment focus. Either way, we'll have to wait see if the company can persuade users that bigger is better.
