In a growing market of Chromebooks that are super affordable and ultra-reliable, it’s refreshing to see a Windows device maker release a laptop designed with portability and affordability in mind. The  Asus VivoBook E403NA is a $399 (about £289, AU$519) Windows 10 laptop that’s designed for those who don’t need a cutting-edge laptop.

Granted, the race to the bottom for a device that runs Chrome OS isn’t something Asus, or any of its fellow hardware makers, should strive for with a Windows 10 laptop. It’s hard to imagine a $200 or £200 Windows 10 laptop being all that impressive.

Instead, the VivoBook E403NA is among the few Asus laptops that compete with a fellow low-end Windows laptop in the Acer Swift 1, along with a well-refined Samsung Chromebook Pro. Both devices are priced in the same area, and offer similar experiences; Chrome OS notwithstanding.

Price and availability

With Chromebooks having a grip on the education market in the US, it’s not hard to believe the VivoBook E403NA is only available in the US. In the UK and Australia, Asus sells similar, yet far more expensive and powerful models.

The specific model we received – the E403NA-U21 – is one of two models listed on Asus’s online store, and is priced at $399 (about £282, AU$518) for 128GB of storage and with Intel’s Pentium N4200. For just $250, the E403NA-US04 cuts the storage back to 64GB and boasts the Intel Celeron N3350 processor.

Comparatively, the Acer Swift 1 can be found for as low as $364 (about £247, AU$469) at the time of writing. This particular Swift 1 comes with an Intel Pentium N4200, 4GB of memory and 64GB of storage.

Meanwhile, the Samsung Chromebook Pro offers an impressive 12.3-inch 2,400 x 1,600 display, 4GB of memory, 32GB of storage and is powered by an Intel Core m3-6Y30, for $509  (about £359, AU$655). Don’t let the small storage allotment fool you – Chrome OS relies heavily on cloud storage, and because of that most Chromebooks offer little local storage.


The lid of the VivoBook E403NA is silver, brushed aluminum that wraps around to meet the front of the display housing. The base of the laptop is also encased in brushed aluminum, surrounding the keyboard and touchpad. The bottom of the base is made of black plastic with four rubber ‘feet’ to hold the computer off a table or desk.  

Without any complicated cooling system, the VivoBook E403NA is a measly 0.7 inches (1.7cm) thin and weighs just 3.3 pounds (1.5kg). This laptop is more than light enough to pack around on campus without causing back pain, but still boasts a 14-inch display in a housing that’s just over 13.3 inches wide.

There are a fair amount of ports on the laptop. On the right side, you’ll find an SD card reader and a USB 2.0 port. On the left side are the charging port, a full-size HDMI port, a USB 3.0 port, a USB-C port and a 3.5mm audio jack.

Below the full-sized keyboard is a touchpad with a fingerprint sensor tucked into the top-right corner. A small line along the bottom of the touchpad serves as a reminder for which side of the pad represents a left or right click.

Alas, here we have another Asus VivoBook laptop – and another frustrating touchpad experience. The issues come from an oversensitive right-click recognition, one that randomly replaces a standard click when attempting to select an item with the option menu.

This is the same issue we’ve experienced on the Asus VivoBook Pro 15 and the VivoBook S510U. And, yes, the fingerprint sensor in the top-right corner of the touchpad is an awkward spot for such a feature. The power button, just above the keyboard in the top-right corner, would be a far better spot.

In other words, if you do pick up a VivoBook, make sure to buy a mouse, too.

Meanwhile, the keyboard lacks a backlight, a frustrating omission for those who tend to rely on visually seeing the keyboard in a low light environment. An extra column of keys to the right of the Enter key are where you’ll find Home, Page Up, Page Down, and End keys.

The added row can be helpful, but often we hit the End key on accident when we intend to press Backspace. Undoubtedly, a bit more time with they keyboard will lead to an adjustment.

All told, the keys are a bit squishy, but don’t interfere with error-free typing as we have come to expect from similar keyboards.

Despite a Full HD (1,920 x 1,080) display, we find this laptop's screen disappointing. The colors are overly muted and lacking in vibrancy. 

It’s understandable that hardware cuts need to be made to hit a price point, and while the display isn’t a deal breaker, it is one area we would be willing to pay a little more for a better screen.

Additionally, even though this is an entry-level device, it would have been welcome to have a touchscreen – especially considering the need to compete with Chromebooks.
