>> 100MB is quite a lot if you live in the third world where bandwidth is expensive.  Would it be more efficient to download the 700MB iso for the OS, then download and reinstall all the extra apps, or upgrade?  Can't say unless you know which extra apps, but is there a way of finding out in advance?  For example, I have quite a few apps that aren't included in the distro, but I can't tell how much difference the upgrade vs reinstall options will make.  (Actually, it's of academic interest to me at the moment because I won't be upgrading or reinstalling until the next LTS (Putrid Panda?))

Not really.  It will give the size of upgrade including all the upgrades required for installed apps, but it won't
give the *difference* between upgrading and reinstalling.  To get that, I suppose one would have to look at
the size of the upgrade and compare that to the size of the ISO plus the download size of each app plus a
bit for upgrading packages after install.
