So doing a bit of playing around with Elementary. I got it installed on a big USB SSD drive I have and it's working well.
Except, installing non-curated software from the Applications tools results in very old versions of the software being installed.
Installing GIMP via the App tool installed v2.8 whereas the latest is 2.10.20 Installing Digikam installed v 5.6 where the lastest is v7.0
Getting the latest of these two installed was a bit of a flail with a goodly amount of digging and command line activity beyond a simple apt-get install. GMP was not too bad, Digikam was a struggle.
