What about TailsOS? You can boot it from a thumb drive and use it as a desktop offline signing device (I know it has electrum support and maybe Sparrow?), similar to a hardware wallet.

That's a good shout, cheers.

So its a viable solution?

Also cheaper than any signing device or phone, will you be taking a laptop with you?

I might take my laptop just so I can access Sparrow.
