Other reviewers have said that you don't get the whole magazine when you get the Kindle edition, but this actually isn't true so I thought I would clarify. The issue here is with the layout of the Kindle edition. For the Kindle, you lose the magazine format and everything is instead linear like a book. The first 20 pages or so are reader comments and summaries of blog posts from the online edition. I imagine in the print edition it is more clear that this is just a discussion section (I don't currently subscribe to print so I can't say), but on the Kindle it reads as if you are just getting condensed articles. If you just stop here without reading on, it really will feel like you're not getting the full magazine. The real content, however, is still there! You just have to use the directional pad to skip the first few sections - same navigation system as found on the Wall Street Journal kindle edition, if you've ever used that. If anyone at HBR is reading this, it really would be helpful to move these sections to the end of the magazine to reduce confusion.
Now for my review. Navigation quirk aside, I'm still giving this five stars. I normally read this on my android phone, and on there the magazine is beautiful, in color, and easy to navigate - if you have an android, I definitely recommend it. The content is unmatched and definitely worth the 6 or so dollars you pay a month.
