I had Peppermint 3 cd but not Peppermint 4...so installed as temporary measure,but it is blistering fast so now I do not know whether I am going to install 4...leave well enough alone.

Peppermint 4 is equally fast, but if you're happy with Peppermint 3 you could always just stick with it until Peppermint 5 comes out later this year.

Up to you .. personally I prefer Peppermint 4 to 3, but it's a "personal" thing, others still use Peppermint One andd Ice

Well, I bet that was of NO use helping you decide eh

If you have a recent Android phone .. MTP works out of the box in Peppermint 4, but not Peppermint 3 <-- did that help
