I guess I've gotta be the 'fly in the ointment' here..!
Yes, Linux Mint is a very good distro, no denying that.....for people who just want to get on and do stuff. At that, it absolutely excels. But, like all the 'buntu-based distros, the continuous slew of updates always broke things on my old Compaq.
(And no, I have no intentions of upgrading to a newer machine any time soon...)
I've always been a natural-born 'tinkerer'. Which is why I love Linux so much. And no, Puppy doesn't have all the 'smoothness' of many of the most popular distros. Yes, it does need a lot of stuff to be set-up the way you want it to run.....but it only needs doing once. And once only.
Most of you have, I guess, by now seen some of my customized desktops. I probably spend as much time on them as I do in setting Puppy itself up. But I do what I do because I enjoy it.
For a 12-year old machine, running on DDR1 RAM, Pup beats everything else hands down. On this hardware, it absolutely screams. It may look like Windows to some of you here.....but, like Windows, it has wizards galore, and tooltips everywhere you look. Which is, I think, why we attract so many ex-XP refugees; it seems familiar. For many people, that very 'familiarity' makes all the difference. And, like any Linux distro, you can make it look anyway you want it to.....

I don't need, much less want, to look anywhere else..!

I with you Mike why change to newer hardware when what you already have does what is needed.
I to enjoy keeping my old hardware alive and building a new desktop in my case to run the web just isn't going to gain anything for what I use my computer for.
Lots of older hardware still around that is very usable and can be had for almost nothing.
Many other choices with Linux if the mainstream ones won't run on my hardware.
Yeah Ubuntu 14.04 is OK and it was my first Linux Distro so I keep it until it is no longer supported.
I like antix-15.1 Killah P a no nonsense light weight little distro that seems to run on anything without problems and is very fast.
Now Puppy (tahrpup) that is my sport Linux Distro as it just runs and does everything right out of the box at the blink of an eye.
The wife uses Linux Mint 17.1 Cinnamon for the exact reason you stated in your post Mike and I'm glad she is finally away from Windows.
I'm just not impressed with Ubuntu 16.04 and Linux Mint 18 they offer nothing I don't already have with the Linux Distos I'm using now and they don't like some of my older hardware.
Puppy (tahrpup) and antix-15.1 Killah P are my fastest Linux Distros for hardware I'm running them on.
Boot up times and shutdown times aren't a concern to me, how the computer preforms when in use is what really matters.
----------------------------
Found this in trash pile on big trash day replaced power supply fan installed Ubuntu 14.04 runs great. Boot up and shut down times are equal to Condobloke's times.
