Big tablets with built-in styluses are not easy to come by. In fact, Samsung is pretty much the only game in town. The Galaxy Note Pro 12.2 is the biggest and most expensive Note device, but you can get a good deal on it through eBay today. If you're in the US and don't mind a refurb, it's only $499.99.
The Note Pro 12.2 has a resolution of 2560x1600 and packs a speedy Exynos 5 Octa chip with 32GB of storage and 3GB of RAM.
