Slightly misleading.
The complete case files volumes 1 - 20 contains most of the Dredd strips up to around 1994- 95, so to say it brings us up to present times is not accurate, that doesn't even cover half of the published Dredd so far.
You can also get the first five volumes for a tenner each from the 2000ad web site, DRM free (CBZ or PDF format) so you don't need an Ipad to view them. Same goes for the weekly and monthly comics.
