Re: Question [Friendly Advice]
If it's not already 17.3, upgrade it to 17.3.
If it is 17.3, leave it alone; just use the 'update' icon on the panel to stay current.
17.3 is acknowledged to be THE BEST of all the latest MINT distros, hands down; the most rock-solid; the most trouble-free. Newer does NOT mean 'better'.
I have two Lenovos (T430, T420), one running 17.3; the other had 17.3 RE-INSTALLED after trying out the "new, improved" version. The MINT Linux organization set the bar really high with 17.3.
