Cons
Con Computers may have man-in-the-middle adware installed
Lenovo is shipping computers preinstalled with man-in-the-middle adware called Superfish. It's a web proxy that can hijack any web session, including encrypted/https sessions. And since the root certificate is the same for everyone with private key present on the machine that's now publicly known, anyone can spoof any site to people using Lenovo laptops. Currently, it affects IE and Chrome browsers with Chrome expected to push an update that will block the certificate soon.
Uninstalling Superfish won't remove the certificate.
Lenovo are standing by their choice to install adware.
Con Some issues with the trackpad in Linux
Some users have complained about the trackpad drivers for linux, but there have been workarounds made and official fixes are in the works.
