WP8 has some issues:
- Interface is cluttered by the use of so many tiles
- Tiles that change all the time make the UI inconsistent, against all Human interface guidelines
- WP8 doesn't support the latest hardware available
- Multitasking still sucks
- There are very few updates and no real roadmap. Microsoft is moving slowly with WP.
- Internet Explorer mobile is not bad, but not as good as Safari.
- Apps are still a big problem (or the lack of them)
It all depends on perspective.
I love having a lot of tiles, the more the better. Since they are square they seem extremely organized, even with a lot of them on screen.
Tiles that change all the time are genius IMO, you can instantly see information at a glance, far better than widgets IMO, and anything is better than iOS static icons (why is it always 73 degrees and sunny?!?! doh).
