Best answer: The best digital stylus that you can get for the Dell Latitude 7400 2-in-1 is the Premium Active Pen. It offers four times the pressure sensitivity as any other Dell pen, as well as a handful of other advantages, too.
- Cream of the crop: Premium Active Pen (PN579X) ($100 at Dell)
- Affordable alternative: Active Pen (PN557W) ($65 at Dell)
What makes the Premium Active Pen so great?
The main reason that the Premium Active Pen is better then other options for the Dell Latitude 7400 2-in-1 is that it has two times the amount of pressure sensitivity. Where Dell's other digital styli only have 2,048 levels of pressure sensitivity (some only have 1,048), the Premium Active Pen has a whopping 4,096 levels. This means that you can make more nuanced and precise strokes with the Premium Active Pen, which is something that artists in particular will love.
In addition to the pressure sensitivity, the Premium Active Pen also comes with three customizable buttons, which is an upgrade from the standard two that Dell's other styli have. Also, the pen has tilt support, which means that you can tilt it on an angle and it will still work flawlessly.
Lastly, the Premium Active Pen is multi-mode and can work with devices that use Microsoft Pen Protocol (like the Surface line) as well as AES 1.0 and 2.0 (what the Dell Latitude 7400 2-in-1 has). This gives it an excellent range of versatility that you'll love if you own a Microsoft Pen Protocol device.
What if you want to save money?
If you don't want to spend a lot on a digital stylus for your Dell Latitude 7400 2-in-1 or simply don't need the bells and whistles that the Premium Active Pen offers, you should opt for Dell's regular Active Pen. It only comes with 2,048 levels of pressure sensitivity and doesn't have any of the features that the Premium Active Pen does, but it costs a lot less and will still work great for basic actions like note-taking, doodling, or tapping.
