I have to admit, the old site was better, by quite a significant amount! It was nigh perfect for viewing on an iPad, mostly because of the fact that it didn't need flash or anything to do it.
As for downloading issues, you can't do that at all, as mentioned in their FAQ...
Q: Can I save the online edition to my computer as a PDF file?
A: Not currently. We would like to provide such features but are concerned that they would encourage unauthorised distribution of the magazine.
So, I honestly don't see this happening at all, which is sad, because that's one of the features that would definitely convince me to use the digital edition, so I didn't have to wreck the magazine.
