I loved the Windows Phone too.

I was one of two non-MSFT I knew of that had one.. and I bought it because an MSFT employee was showing it off and I was convinced. The concept of Tiles was great and Cortana was respectable. It felt comparable to Siri and way better than Google.

I used it for a couple years until the apps I needed started disappearing due to lack of updates.

I really wish I had messed with Windows Phone when it was a thing. They were the only ones not to just ship a clone of an existing interface ASAP. But it was closed source and offered no advantages for carriers or device makers compared to Android.

WebOS needed WASM and a lot more to be successful. I think WASM/WASI is to the point that the next major platform build out can use it.
