Nearly all OEM notebooks ship with some amount of bloatware, although Lenovo keeps it lighter than most. The Modern UI of the Twist is loaded up with a few apps by default, like Kindle, Evernote, and Skype... many you're likely to install anyway. There are a few, like Skitch and AccuWeather, that you'll probably get rid of or unpin from the start screen.
The desktop is left pretty much alone, shy of a few Lenovo-specific utilities and trial versions of Norton Security and Absolute Data-Protect. They do bundle in a traditional Windows legacy-style app launcher for the desktop, although it's of little utility considering it froze up on me more often than not. Even when it was working, not being tied to the Windows key made it less than useful. Anyone looking for that functionality will find far superior alternatives in the Windows Store.
