If you've got a paid subscription (plan prices haven't been announced but are expected to start at $19 per month), the service kicks in automatically when you're disconnected from Wi-Fi and goes dark when the Wi-Fi's live. The service works well--or, at least, as well as the 5G signal is in your area. In my house, cell service is spotty, and HP Go was hit or miss. But on the road, in a beachfront rental with decidedly shoddy Wi-Fi, HP Go worked great, providing me with a reliable backup connection when I needed it the most. HP Go is installed on a laptop, though it seems almost incidental to the main event. The EliteBook 6 G1q is a Qualcomm-based system, with rather pedestrian specs that are similar to what was on the market a year ago. The now-snoozy Snapdragon X Plus X1P42100 anchors the Windows machine, backed up by a healthy 32 GB of RAM and a sad 512 GB SSD (in the test configuration I was sent). The 14-inch screen packs a low-end 1920 x 1200 pixels of resolution and one of the dimmer backlights I've encountered in recent history.
