I got rid of the language translator & youtube since I use tubemate.
Uninstalled Talkback, Google Play books, music, movies & magazines.
Froze Weather, Swype, Update Device, & Sprint Installer, I did the last 2 in hopes it would stop the OTA updates but still get them.
I've used Titanium Backup for a long time & sometimes if you uninstall an app it may not be able to restore it so if you're not hurting for space it might be better to freeze them.
This is my 3rd Boost android & I'm surprised how little bloatware it has compared to my original Galaxy Prevail
