This is definitely the way to read IEEE Spectrum. I used to download the PDFs and read them in a viewer, or sync them to my iPad, but this app provides a great way of seeing all past issues you might have missed, downloading the ones you want, and start reading. About the only way it could be improved is with a way to read the text in one column with adjustable font sizes.
