I've been obsessed with the iPad for some time, but really wonder if it would be too extravagant a purchase, given what I already have. I have a year-old Macbook Pro upgraded to Lion, an iPhone 4 bought a few months ago, and I use the latest Kindle for reading. Have already used my Kindle for reading books because I get eyestrain with backlit reading for long periods. I'm in love with the magazine demos on the iPad I see on TV shows. Recently I tried using Zinio to read a few free magazines on my Macbook and it was no better than working with a PDF document. Are magazines different on the iPad? I know I don't *need* an iPad, but what would I really gain by purchasing one? FWIW, I use my Macbook mainly for Internet browsing, reading news, and email. Thanks.
