configurable within Windows, but there’s no
erasure capability. The only way to “erase”
e-ink is to slightly depress the top of the
barrel-mounted button. Otherwise, though,
the e-ink latency was minimal.
Dell’S WM527 is essentially a Microsoft
arc mouse, though with a thumbwheel and
without the ability to fold flat. A mouse that
balances fore and aft rather than with a solid
base sort of creeps me out, but it’s truly
ambidextrous, with a side-mounted button on
either side. You can connect either via
Bluetooth or with an included
wireless dongle. It runs on a pair of
AA batteries.
Dell’s WD19TB Thunderbolt
dock, meanwhile, demands a
sizable portion of your desk for the
expansion ports it offers. Weighing
1.29 pounds, the dock requires a
footprint of 8.1 x 3.5 inches. Though
the Latitude 7400 supplies a
number of ports, the WD19TB
provides many more: a pair of
DisplayPort connectors, an HDMI
connector, two USB-C 3.1 Gen 2
ports, 1 more generic USB-C port,
and a Thunderbolt 3 (USB-C)
connector, too. Unfortunately, you’ll
need to figure out which is which, as
they’re marked with somewhat
cryptic glyphs (an “SS10,” a
DisplayPort “D” and a lightning bolt)
that don’t quite make clear what

Dell’s WD19TB dock is definitely one to leave on your desk,
and not in your bag.


Dell’s PN579X active pen registers 4,096
levels of pressure sensitivity, with a 240Hz
report rate. Though the Latitude 7400 2-in-1
doesn’t include a dedicated holster to stash
the pen, both sides of the 7400 are
magnetized to grip the pen when not in use.
There’s also a lanyard in the box, as well as a
SIM removal tool.
While the PN579X does offer tilt support,
it wasn’t functional on the Latitude 7400. It’s
an odd pen, too: The top-mounted shortcut
button serves as an app launcher,
