yes, i'm reading tons of magazines on the ipad.
In fact, got Zinio with subscriptions. But the zinio-app just doesn't work well (slow), so i downloaded the pdf-files online and read it with goodreader.
The screen is very well readable. But for maxim, the fontsize might be too small. Luckily you can zoom really easily and fast with the ipad.
(oh, the ipad is great for travelguides and manuals too
)
