As a long-time reader of the IHT I will not dwell on the excellent contents except to say that this paper belies the idea that trusted, authoritative, balanced sources of information are not worth paying for, and refer for this topic to reviews on the hardcopy edition.
I carefully checked, article by article, the paper and electronic versions. What is missing from the Kindle are most pictures, the comics, the games/puzzle sections and all ads. All the articles are in, unabridged. It gets faithfully delivered here in Geneva six days a week, at around 4 am (...is there when you wake up). Unlike the hardcopies, delivery is not delayed by local holidays, "follows" you in about any country your Kindle may travel to and saves you serious money. What is particularly convenient on a Kindle is the possibility to clip citations (or even entire articles) and looking up words in a dictionary; you may even have the paper read aloud to you. The IHT can conveniently be navigated by sections, or you can just hop section by section through it all and read only those you want.
When buying a Kindle I had this IHT subscription in mind and have never regretted this since.
The slight drawback is that the IHT will not grant you web-access to back issues. However, if you really want this you can simply keep all your electronic issues on your Kindle or on a PC for later retrieval and clipping.
