I'm sort of concerned about the status of the Mycelium team/wallet, as it is currently my go-to platform for mobile spending with the Trezor. Mycelium's integration with the device is pretty much flawless with the exception that the ios version is pretty gimped in many respects.
Recommending the Trezor to a friend, I was quick to discover limited options for mobile spending due to few (if any that I have seen) mobile wallets that integrate with Trezor the way Mycelium does on Android.
The thought occurred to me: Trezor, why not develop and maintain light wallets for Android and ios so that spendability is merged across the desktop and mobile spaces? This gives Trezor better control over their brand, and might allow more innovation in the hardware wallet platform while depending less on third party wallets that might not interact as seamlessly with a Trezor product the way an proprietary mobile wallet would.
Overall, I am very, very satisfied with Trezor and want more from them!
