wallet would initially provide Blockstream Green support for Android only
Blockstream Green mandates multisignature, in which Blockstream hold one of your keys, so it seems the only way to use this hardware wallet is to give Blockstream some control over your coins. It seems from other press releases that when they talk about desktop and iOS support, they are only talking about support for Blockstream Green on those platforms. That's a pretty big flaw for a hardware wallet as far as I am concerned.
Perhaps if and when it can be used with a third party wallet such as Electrum then I'll give it another look, but if that never happens then I'm never touching this device. What's the point of a hardware wallet if you still need permission from some third party to be allowed to use your coins?
I was just going to say almost the same thing, but exactly what o_e_l_e_o said.
About 5-6 years ago, I just bought a new computer and printer for cold storage that never touches the internet. While these hardware wallets are nice, right now I am more comfortable with a specific portable that is used for cold storage and doesn't rely on a third party to access the coins. I'd prefer to have full control and not have, essentially, a black box.
