No, I think that the point of this request (and several other identical ones in the past) is that the LTS version of Mint is still being recommended by Clem, and consequently is still being downloaded and installed by users. There are a tremendous number of updates for that original Mint 13 version; it takes quite a while to download and install them all immediately after a new install of Mint. Ubuntu updates its LTS iso's, keeping them much more up-to-date; it would be nice if Mint did the same. I realize that this is unlikely to happen due to the lack resources required to re-test each ISO, but it is a valid request.
The amount of time required to update a new system may be a trivial issue to most of us when installing on our own PC's, but at times it can be critical. I install Mint for other people (mostly family members), and usually I am pressed for time. I try to squeeze in an install of Mint in a much-too-short visit, and have occasionally had to leave an install in its original state with no updates. I have little confidence that the PC's owners ever update their machines, as they are not tech-savvy at all.
Another issue is actually more important and less of a convenience one - Mint 13 doesn't install properly on all machines due to its kernel. A good example is the Broadcom situation - I have one laptop that I can't install Mint 13 on, despite the publicized work-arounds. I can't even try Mint 14, since the laptop requires a non-PAE kernel despite having been bought in January 2006 (it has an AMD mobile Sempron processor.) I run Mint 9 Gnome and Mint 12 LXDE on it, but can't go any further. Fortunately, it's only one of five PC's I have (none are particularly new, though), so it's not all that important to me, but I'm sure that I'm not the only person who has an old PC that can't run a more modern and demanding version of Linux.
I've tried creating my own updated ISO's by following the "How to remaster/respin Linux Mint ISO images" tutorial, but it doesn't work for me (or for a number of other people, based on posts I've seen.) I've tried it several times over the past year, but I can't get the chroot terminal to open properly.
