Not sure where or how they are publishing the digital version, but your complaints about that format don't seem to apply to the books/articles I've read on my iPad or the Kindle apps. Every e-reader app I've used has prefs or settings for selecting font sizes/font family/background color/etc.. 'Pages' are flipped by swiping, not touching/clicking on arrows. 'Pages' can be bookmarked very simply and found easily. They can also be deleted if you only want to use one to mark where you last read. However, bookmarks can also be used to create your own "index" of items you want to view repeatedly.
Access to images/video/related info/etc. are actual 'links' that can be used to go directly to that extra material, as long as you have Internet access.
As far as I know, you can't do any of that with paper.
e-Books are basically just a stripped down version of html. So links are links, scrolling is scrolling, etc. But html, itself, has a great deal of limitations. For books/print, the biggest one, in my humble opinion, is the lack of available fonts. Most great fonts cost money to license, so the fewer included with any reader, the cheaper it is. Of course, an e-book reader usually has at least five or 10 fonts to choose from, paper has one. And, every time an editor decides to change the normal font, there are hundreds of complaints!
Images are often extremely important, but e-readers have limited memory and pixels, not to mention colors, available unless you pay for an iPad or expensive tablet. Of course, an image might be replaced with "a thousand words"!
As for Macworld, I stopped reading the magazine quite a while ago. Reviews were always months out-of-date. Tutorials usually lacked enough images and could never match a video. There was very little input from real users. Answers to problem was always limited to a small handful of specific topics which were further limited to the most common apps/hardware which may not have applied to me, at all. Technology simply moves too fast for a typesetter to keep up. Then there is the time delays of printing and mailing, not to mention the damages that can be done by the USPS, assuming they even deliver the magazine to the correct address...
Have we come to the cost of paper and ink, yet?
Hey, you want printed paper? Buy a printer!
See how much that will cost you. And it won't cost me anything for your copy!
BTW, an iPad will work in most bathrooms...
