Pro Friendly and helpful forum
Pro Looks great
The XFCE Whisker menus and dark theme are well designed.
Easy to move the panel to the top and add plank on the bottom.
Pro Fast and light on resources
Ram Consumption is the same as LxLE, but more efficient and because of Whisker Menu and other tweaks that let us feel more like we have a XFCE desktop environment, as keyboard shortcuts, for instance, it looks like we'got here the fastest and lightest, globallty speaking. Very good on performance. Download Respin 7 (march 2017), install Libreoffice and then compare, for example, openning Libreoffice Writer inside Peppermint 7, Extix 17.04, Lubuntu 16.10, Xubuntu 16.04, Backbox 4.7, Linux Mint 18.1 Xfce an Mate or Linux Lite 3.4 (and others, I've tried many distros). Finally, you'll find out that after openning a few apps in Peppermint remains it smooth and light. Nemo file explorer on Peppermint is incredibly faster than in Mint Cinnamon; lx terminal is very fast oppening; updating is fast. And after all distro keeps working and working very solidly and consistently along the time. And yet the look and feel environment is pleasant.
Pro Comes with a variety of helpful tools
Works great with teamviewer, synaptic, XNview, KODI and Pdf-Xchange editor (via playonlinux). Netflix works awesome with chrome browser. The ICE SSB tool is great for creating web apps that run as if you installed them locally.
The Software Boutique (packaged with The MATE Welcome software Center) recognizes all the software and installs them in one click.
Pro Peppermint 7 is stable
Peppermint 7OS (32 and 64 bit) has been updated to the Respin PPA . Kernel updated to 4.9.24 on 23-April -2017 with no issues and all software still runs great.
Con Not built around the desktop experience
SteamOS is, first and foremost, meant to act as a gaming console - it doesn't ship with even some of the most basic applications, such as a file manager or image viewer. As a result, using SteamOS as your primary operating system would require a fair bit of work.
Con Hard to install
If you've installed Arch you're probably fine, but for those used to simple installs like (Ubuntu to name just one) you should prepare some patience, determination, and painkillers. Good news is, it's getting better (it's very young).
Con Since it is based on Lubuntu, the double click speed needs to be slowed down
It's false that Peppermint 7 is tout court based on Lubuntu. Take a look at ths: "Peppermint Seven makes use of the Xfwm4 window manager, and Xfce bottom panel in the LXDE desktop environment. This is unlike other Linux distributions that use LXDE as the default desktop environment where it is common to use the Openbox window manager, and lxpanel." And more: "Peppermint Seven is built on the Ubuntu 16.04 LTS code base and makes use of its package repositories." Contrarily other linux distributions Peepermint creators never said Peppermint 7 is based on Lubuntu, like LXLE. Using LXDE and being based on Ubuntu is very different of being simply based on Lubuntu. In fact, Lubuntu is not faster than Peppermint and has loads of lacks for a nowadays OS experience.
