Zinio. One issue is a bit over 2 Pounds Sterling like the paper version, not very impressive. But then fifty issues, a full year, is only 25 pounds. That's more like it!
Zinio seems like a good service. Buying was quick and simple, like the best online shops I have tried. Second time I bought I didn't have to type in card data and such, only my password.
And delightfully, the digital magazines are not scans, not even very good scans, they are full PDF files (or PDF-like), meaning when you zoom in on the text, it's dead sharp. That's lovely for readability.
And it gets better, you can even click a little "text" button to see only the text in one wide column, a choice of two text sizes, so you don't have to scoot the page around on the iPad to follow the meanderings of the columns between the pictures and ads. This goes above and beyond the call of duty, I give them an A for this.
... All right, perhaps A-minus. Sometimes it's tricky to coordinate where you are on the text pages compared to the graphic pages (the "text" button sometimes isn't there). And it would be nice with more choices for text size and fonts. And if they were to really perfect it, they might put in the pictures on lines by themselves in the text view, like Instapaper does it. Best of both worlds.
