Zune
No Google app suite, which Google is absolutely allowed not to make. So Microsoft made the apps for free for Google, google said no, then Microsoft released their own brand clients (e.g. Microsoft YouTube client, Maps, etc) and Google shut it down with lawyers.
Can any platform survive without Google ecosystem support? If Windows Phone was the case study then likely not.
iPhone 4 was released before WP7.
It’s a shame, my WP8 phone is still my favorite smart phone ever.
Store curation was also an issue with tons of garbage in there that shouldn’t have been allowed.
The photos app was amazing. Live tiles are amazing. The music player and it's live tile was amazing. The performance was the same whether on a low end budget phone or the top of the line model.
So many good ui and ux decisions like the lack of hamburger menus and placement of all menu items along the bottom of the screen with the extra items being hidden away in a drop-down using ellipsis. System wide light and dark themes jazzed up using an accent color that all of your apps respected.
The People hub (contacts app) was the central point for all social media. Facebook and Twitter were integrated. I didn't need fb messenger. Skype and fb messenger were integrated with the messaging app.
Damn, I wish we made it.
On the other hand, it would have gotten a -7 rating on the ifixit scale. The hard drive got jostled one too many times and stopped working properly. I've fixed a lot of phones, but the Zune turned out to be unopenable, if that's even a word.
Actually, that's a lie. It did ultimately open, but the casing cracked repeatedly.
