I just love Zinio. Personally I use it on my Mac desktop and also the iPad. The whole Zinio thing not only saves on paper and our forests, but reading on your electronic device is so intuitive and you get extra features too.
Currently, running through to the 31st Jan 2011, there are two fantastic offers from Zinio to celebrate Macworld:
1) Read for FREE- go to zinio.com/macworld and enter the code macworld for a free issue
2) Subscribe for 20% off – go to zinio.com/macworld20 and end the code macworld for 20% off tech titles
