I finally got the Focus and used it for a day over the weekend. Using the Atrix for work today but when I go home I'm switching back and updating to NoDo
As far as comparing it to the iPhone, I think the OS is very similar and Microsoft certainly took a page out of Apple's playbook- limiting user customization in order to eliminate instability. Which isn't a bad thing. Need more apps though, which will come in time but some apps I expected to be there already.
