1. The Jade Plus is a big improvement all around. The metal version is a bit weightier and feels nice, albeit less stealthy (it's metal). The nav buttons need an upgrade; currently feel sticky and not very tactile. Screen is great. Cam is great. I want to see NFC next, vs USBc/BT/QR modes.

2. The Jade Plus is for managing offline keys, you still need to interface with Green or other option (like Sparrow etc). Those things must be installed on a computer. #GrapheneOS, especially dedicated, is going to be easier to maintain and more secure than a laptop for this purpose. You can use QR mode to prevent a direct connection between the Jade Plus and the signing interface on the device. The coupling is very loose; so I wouldnt characterize it as "linking your hw with your phone". Plus, this is a dedicated device for this purpose only, not my daily driver.

nice, my main reason why i use a computer is that i can run a node on it, so are you connecting your node to the phone or you using a public node ?

i didn’t know that a dedicated grapheneos phone is more secure than a laptop

For a node, I recommend the Start9 Pure which can run 24/7 - https://store.start9.com/products/server-pure

A laptop which fully contains the entire setup is a good option if you know how to secure it. I have a setup like that as well (Fedora Silverblue + Sparrow + Start9 in VM).

Just got Jade Plus, here’s my “before plugging it in review” and @Laser is right about these buttons:

Buttons:

- Weirdly sticky. It’s a consistent millisecond stick.

- Too much lateral wiggle. I have a full 1mm of lateral wiggle on the button near the lanyard hole, not the other.

- The two identical buttons click differently.

- Click sounds hollow, you want a tighter, denser click.

Buttons are important, just like the car door close test in auto sales. They are a tactile and sensory indicator of overall build quality and the user’s physical connection to what’s within. It’s so important to satisfy visual, auditory and touch with buttons. If I’m sending sats, I want it to feel like I’m sending sats!

If you want tactile buttons, look to the hardware synth community, these guys are obsessed with this stuff.

Camera:

Something feels a little cheap where the plastic meets the lens cover. I’d like to see that whole top 1/3rd casing be camera glass. Consider aligning lens centre with the center of the side button.

**The Good

Weight:

Wallets should have heft, this metal one does and it makes you feel important.

Minimalist design:

Great to see just a clean logo with no “Blockstream” text. This signifies confidence and a nod to stealth.

Body Machining:

Smooth and well fitting
