This is less of a question and more of a suggestion for Microsoft. The disconnect between Windows 8 apps like the version of IE on the Start screen and the version of IE running in desktop mode is confusing. I'm concerned it will become an impediment to adoption. These two worlds really need to be integrated.
Here's a confusing use case I just experienced.
I started IE from the Start screen and navigated to Pandora. Music started playing and when I switched back to the Start screen it stopped which made it feel like the Surface can't multi-task. Wondering if the music would continue when I switched to the desktop view, I noticed the IE icon on the taskbar in desktop view. When I launched IE from the desktop, I had to log in to Pandora again, which seemed weird and highlighted the fact that the Start IE and the desktop IE are in two different worlds. I've also been confused by the fact that the icons in the taskbar in desktop view don't show the running Windows 8 apps. To see those, I have to use a new gesture to see the running Windows 8 apps. This list of running Windows 8 apps doesn't contain any of the applications I've launched from desktop view.
Integrating these two worlds may be one of the single greatest changes you can make to Windows 8 to help alleviate barriers to entry for this otherwise very useful update to the OS.
