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. It runs Android 4.4 and has all the necessary optimizations for the S Pen inductive stylus included in TouchWiz. You get your choice of white or black devices with this deal as well.
The Note Pro 12.2 has a list price of $749.99, but regularly sells for $649.99 new on Amazon. An extra $150 off isn't a bad deal for a refurb, though. Shipping is free, but this is US-only.
