I've seen many Android-powered smartwatches out there with capabilities to run apps in the same way (almost) as an ordinary smartphone would. On the other hand, we have the Apple Watch which runs its variant of the iOS system. Imagine being able to install a lightweight wallet like Electrum on a smartwatch to send/receive Bitcoin transactions. After all, most of these (if not all) smartwatches have Wi-Fi capabilities, Bluetooth, and more. By integrating Bitcoin wallets into smartwatches, you can truly send/receive transactions anywhere with ease. I'm sure not if this is possible yet (as I don't own a smartwatch). But if a developer decides to create Bitcoin wallets for smartwatches, I'll be a big hit within the mainstream world.

What are your thoughts? Is something like this practical/secure? Or is it better to continue using smartphones for Bitcoin transactions?
