The only issue I ran across so far was a crazy-fast battery drain. Once I dug under the hood a bit it wasn't hard to find the culprit. Background tasks. After turning some off manually and removing a few apps it cleared itself up nicely.
I can see where having those apps together on one screen can be handy - minimal swiping to get where you need to go.
On the flip side, that is extremely cluttered and looks like the Windows Phone OS ate a bit of Android 2.3.7 Gingerbread and crapped it out over the phone screen.
That might be just about the same number of apps I have on my entire phone. Do you need a recipe app on the start screen up top? I plan on having medium sized tiles of my most needed at top a large for calendar and then small below. The start screen does scroll.
