I have about 12 magazine subscriptions on Zinio that I read on my MacPro, MacBook pro and iPad. I've used Zinio for over a year. I also have a Kindle.
I like Zinio because I like all my mags in one place (as opposed to using different publishers' websites or readers) and also I like their selection of magazines better than what Kindle offers.
I travel a lot and usually end up accumulating several unread magazines and magazine articles as well as other old issues and articles that I want to keep and read again later. In other words, I'm not the type of reader that reads the magazine the day it arrives and then trashes it when it's a month old. Like in the real world, I like to have a stack of interesting reading to go to when I have some spare time or when I can't sleep.
So ..... I have reoccurring frustrations with Zinio. Every few months the files get corrupted or whatever and the program freezes and refuses to work. Then I have to trash everything and re-download the software and also redownload all my magazines (past issues). With over a year's worth of 12 subscriptions the download size continues to increase.
BTW ... I'm using OSX 10.6.8 . I'm not using Lion. All my Mac's are less than 18 months old ... lot's of RAM and HD space.
Zinio's short fix for a program freeze is to simply trash Adobe Air and reload a fresh version (Adobe Air). However this has never worked for me and I instead must trash the Zinio program from my computer as well as all the pref files and the cache files (including the downloaded mags). I don't always have access to fast internet and this process can be a major hassle, especially when for instance I'm traveling or planning a trip and want to read that travel article I saw two months ago. I've had to do this for both my MacPro and MacBook Pro several times, Zinio has done this freeze on the MacBook Pro twice this month already ... so far Zinio on the iPad has been OK but I also don't use it so much.
I don't know if these problems are related to Adobe flash. Perhaps.
I also wish that Zinio would allow users to simply download the mags, in PDF format or whatever .... so when their reader program freezes, we wouldn't have to download the entire library again again and again. I realize that with this solution, the piracy issues raises it's head and so probably it will never happen.
