Modern tablets come in all shapes and sizes, and even more variety may be on the way. SamMobile has published purported details on several upcoming Samsung slates, including two models with 11" screen. One of those will be the Nexus 11, which is being built in cooperation with Google and should run a stock version of the company's Android OS. That machine will apparently feature an 11" Super PLS panel paired with Samsung's octa-core Exynos 5410 processor. There's no word on the pixel density of the display, but we can probably expect a resolution of at least 2560x1600. The existing Nexus 10 has a 2560x1600 display, and the Chromebook Pixel boasts a slightly higher 2560x1700 resolution with an unusual 3:2 aspect ratio.
SamMobile doesn't name its source, but the site claims the Nexus 11 will be joined by the Galaxy Tab 11. The Galaxy-branded tablet will supposedly share the same screen technology but sport a less exotic dual-core Exynos 5250 SoC. A microSD slot is planned for the Galaxy Tab, SamMobile says, and the same feature is "rumored" for the Nexus 11. I wouldn't hold my breath for Nexus-branded device with SD expansion, though. Despite the presence of microSD slots on loads of other Android-based devices, the Nexus 4, 7, and 10 all go without.
If you prefer smaller screens, Samsung appears to have several new models in the pipeline. The most interesting is the Galaxy Tab 8.0, which is supposed to have a quad-core Exynos 4412 processor and a 1080p AMOLED display. That model is likely being prepared to do battle with Apple's rumored iPad Mini refresh. The SamMobile story also mentions the Galaxy Tab Duos 7.0, a super-sized phablet with a pedestrian 1024x600 display but support for dual SIM cards.
As smaller tablets in the 7-8" range grow more popular, I wouldn't be surprised to see device makers experimenting with designs larger than 10". Microsoft's Surface tablets are already pushing toward 11" territory with their 10.6" screens, and I suspect Intel's upcoming Haswell microprocessor will spawn a stack of convertible tablets with 11-13" displays. As long as the weight can be kept down, larger slates do have some appeal—especially for couch surfing, where portability is less of a concern.
