I'm considering upgrading from my Nook to a Nook Tablet because I have stacks of back issues of magazines to read. I think I'd save more than a tree if I switched to this method. What do you think of reading magazines online? Is it great? 

I love it!!!

I get 2 cooking mags, and one knitting one.

I am considering getting Nat. Geo.

Its great really, the pictures are so bright. You can make the pages bigger and you can bookmark the pages.

And you also can tap on "Article view" - I believe that is what it is called and it shows you just the print part iof the page so it is easy to read.

I have nothing negitive to say about it.

Love it!  It's what I tell people I love most about my Nook Color.  Just be forewarned, you may not be able to print things like coupons if you have only the e-subscription.  May not be an issue for you, it's only been an issue 2x in a year for me.
