Fujitsu Launches Quaderno A4C: A Game-Changer in E-Notebooks

The launch of the **Fujitsu Quaderno A4C** marks a significant advancement in the realm of digital notebooks. This 13.3-inch device features a full-color **Kaleido 3 e-paper display**, setting it apart from its predecessors, which were limited to black-and-white screens. The A4C is now available for purchase, offering users an impressive range of features that cater to professionals and students alike.

The **Quaderno A4C** is designed specifically for viewing and editing PDF files, making it a practical choice for anyone who needs to annotate documents, take notes, or create drawings. Unlike many competitors that run on various operating systems and support multiple file formats, the Quaderno focuses solely on PDFs. It supports eight colors for highlighting and drawing, which aligns with industry standards. New functionalities, such as the **memorization mode** for learning and a **page-turning function**, enhance its usability, particularly for musicians who can use a foot pedal to turn pages seamlessly while playing.

The **Kaleido 3 display** offers a black-and-white resolution of **1650 x 2200 pixels** at **207 PPI**, with the capability to display **4,096 colors** at a **103 PPI** resolution. This makes the screen not only vibrant but also user-friendly. Its capacitive touch panel supports finger input and electromagnetic induction digitizers, providing a smooth and responsive experience. The device’s design features a white body with a dark grey back and a slightly sunken screen that lacks a protective glass layer, enhancing the visual quality of colors and text.

Included with the **Quaderno A4C** is a dark grey stylus that attaches magnetically to the side. It offers **4,096 levels of pressure sensitivity**, allowing users to create varying line thicknesses based on how hard they press. This feature is particularly beneficial for drawing and writing, enhancing visual organization and learning effectiveness.

Despite its strengths, the **Quaderno A4C** does have limitations. Notably, the display lacks backlighting, meaning users must rely on ambient light when using the device in darker environments. Nevertheless, clip-on lights can be used for additional illumination. The device comes with **32GB of internal storage**, capable of holding up to **10,000 PDF files**, and supports **Wi-Fi** on both **2.4GHz and 5GHz bands**, along with **Bluetooth 5.1** and a **USB-C port** for easy file transfers.

Battery life is impressive, lasting up to two weeks with regular use, which is advantageous for users who are often on the go. The dimensions of the **Quaderno A4C** are **222.8mm x 301.1mm x 5.7mm**, and it weighs **368 grams**, making it portable and easy to handle.

The user interface is streamlined, featuring a main drop-down menu rather than a traditional home screen. This provides quick access to notes, settings, and other features, including a **scheduling app** that allows users to organize their tasks interactively. However, the device is limited to reading PDF files only, which may not appeal to all users.

For those looking to transfer their own PDF files to the **Quaderno A4C**, the process is straightforward. Users can connect the device to their computer via a USB-C to USB-A cable and drag and drop files directly. The PDF rendering engine ensures that documents are quickly accessible and editable, with minimal lag when turning pages.

The **Fujitsu Quaderno A4C**, released in late **2024** in Japan and set for wider availability in early **2025**, is expected to make a strong impact in the e-notebook market. While it may not offer the extensive features of some competitors, such as the **Kindle Scribe**, it excels in PDF management and drawing capabilities, making it a valuable tool for students and professionals.

The company’s commitment to maintaining pricing stability amid rising costs in the tech industry enhances the appeal of the **Quaderno A4C**. As noted by **Michael Kozlowski**, a seasoned commentator in the field, the **Quaderno** brand is renowned for its quality and affordability, positioning the A4C as a compelling option for those seeking a dedicated digital notebook experience.
