IME, the OS and associated MS apps are fantastic, the phone is solid, and I have no complaints. If that's all you cared about I'd say switch today.

But there is definitely an app gap. I was never a huge app user, and most of what I used was there, but I'm pretty sure that's not true for most people. It's pretty hit or miss. You can find Facebook, Teamviewer, Netflix, and Plex, but if you want Snapshat, you're SOL. There aren't even any third party Snapchats around, because Snapchat demanded they be removed from the Windows Store.

There's no first-party Google apps, no doubt a big stumbling block for a lot of people.

I believe the idea of Continuum is targeted to light Office users, people who work on basic spreadsheets and word. It has a target market but I am not sure how big it is.
