I have a free Google Mail app, it works the same way as the regular Outlook app. And if I'm not mistaken, it was made by microsoft. So on my start screen I have 2 email apps. One set up to pull Hotmail, the other set up to pull Gmail

There's a reasonable YouTube app as well, just not made by Google. And a Squirrel browser that's pretty good. But honestly, there's not really a lot wrong with IE Mobile. I mean, these days there's not really a lot wrong with IE desktop. But it still has a bad rep. But mobile doesn't run any differently than the browsers I used on my android devices (default browser and Chrome)

I'm not a huge app consumer. There's 9gag, twitter, facebook, some decent music and video apps, messengers, and a couple anime/manga apps. As well as Netflix and Crunchyroll. And that's about it. There's also a really good solitaire game. But I barely used many apps on android as well. It just sucked that eventually the phones would get so bogged down, I'd end up only able to rely on like 4 or 5 apps, and the rest would close, or stall, or be really slow

If you like to have tons of apps, then there are not a lot to choose from. But the ones they have are super reliable, very stable, very fast. I've had my phone for a long while now, and it's still as fast, stable, and reliable as the first day. I'd never be able to say that about other Android devices. I know iOS stays stable for a few years, so I'd put Windows Mobile in that ballpark for reliability. Usability is more of a per-case basis
