So I don't think the convergence idea is necessarily bad. It's perhaps somewhat niche, and it's not easy to pull off.
I almost never use a phone, so for me the major selling point of my tablet is no Android oddities or second-rate citizen vibes. I don't need to wade through an app store to do simple things. I'm not depending on a hardware vendor where support stops a few years down the road. Plugin a keyboard and mouse, and it's just like any other computer with a really small screen. I already have a desktop computer, so it doesn't replace anything, but the familiarity is still nice.
The touch experience is not as polished as Android. It's fine for my purposes, though. I'm mostly using the tablet as a night-time reader for epubs - dark background, light level at minimum, and then it works surprisingly well for when I wake up and need something to do before I can fall asleep again.
