Is the GPD Pocket 3 good enough as a main laptop?

For most people, no. The small keyboard and screen suit short sessions, travel and field work. Use it as a second machine next to a full-size laptop.

Can you upgrade the RAM or storage?

The M.2 NVMe SSD is user-replaceable, and the battery is too. Memory is soldered LPDDR4x, so buy the configuration you need from the start.

How long does the battery actually last?

GPD rates it around 8 hours, and owners see closer to a workday of light use. Heavy loads cut that sharply, so plan on charging midday.

What is the modular port for?

The side module swaps between a USB-A port and an RS-232 serial port, which is useful for network gear, industrial equipment and legacy devices.

Does it work as a tablet?

Yes. The hinge rotates the screen flat over the keyboard or into a kiosk position, and the touchscreen works with a stylus. It is heavier than a normal tablet.

What comes in the box?

The laptop, a power adapter and cable, and the installed port module. Check which module your configuration ships with, since the serial version is a separate option.
