A tails usb do not raise too much attention, it could be any dummy usb. A dedicated well known HW device immediately will raise awareness.
Will be nice to have a Casio calculator with a hidden option to store some seeds.
Also a HW / cold wallet is not meant to be used as a daily wallet, you are not going to pay a coffee with a Trezor hanged on your neck and each time you want to pay, you plug it into your laptop to sign a tx... cmon... A HW / cold wallet is meant to setup once, extract the xpub (for future deposits only) and close it in a safe place and never use it anymore (only in emergency cases).
Use the 3 levels of stashing: hodl, cache, spend

Oh, right! I remember people playing games on their graphical calculators from Texas Instruments back in school.
Would be cool if they can be repurposed ...
