My view is that in general the magazines have become less and less relevant as information (particularly distro specific stuff) is usually better and more up to date on line.
The cover disks used to be handy in the days of dialup but now the same applies as with the magazine content. I would be happier to purchase a media free copy (at a lower price) but at the current price the content of the magazine as it stands is not justified when the DVD usually ends up being discarded still sealed up.
Also the last few copies of LF I read (about a year ago now) had rather poor hardware reviews which did more to anger me than anything else.
That said I will be downloading the free PDF version just to see if anything has improved (as I suspect is their intent)
