I love this phone, and really appreciate the stock apps to an extent. With the acceptation of the gallery, which is pure junk. I really like the messaging app and the overall feel of the stock setup. To be honest though, the organization from Go Launcher, cannot be beat. For example, if you create folders in Go launcher, and put an app inside that folder, it will no longer be in "all apps", this really makes it easy to track down apps. The stock launcher, although better looking and smoother than Go Launcher, is filled with a crap load of bloatware, and you can't even throw it in a folder for organization.
Just my opinion. It's a great phone, you'll love it.
