I have a Nook Tablet and I love it, but never owned or used any other tablets.
My Nook is a little heavy when I carry it in my purse, but to hold not any heavier than a hard back book.
I like that I can stop reading and go to an app and play a game, then come back to reading.
As for reading options, I don’t care for PDF’s as the print is too tiny for these old eyes and enlarging it (pinch/expand) makes the page off screen. The font can be changed for epub books, as well as the font and back ground color, so that makes it nice to change depending on where or what time of day/night you are reading.
I have used my tablet to use e-mail and watch shows. The sound was great when I used earphones, just ok without. Using e-mail and Facebook it wasn’t very cooperative.
I use mine mostly to download books using the Adobe Digital Edition, from the Library online. I use wifi, of course, to download apps or books from Barnes and Noble.
Fridays they offer a free book and app. They also have free game apps when you search, which is nice. I like the G5 Entertainment apps and the free ones change periodically so I can get new ones and not pay.
I pondered spending the $200 for my Nook Tablet for over a year, could not justify the expense. Then I received it for my birthday! I researched the Nook vs Kindle. Everyone I spoke with liked the Nook better. I now see a lot of free books advertised with the Kindle, but that would fill up my Nook and be the same as filling my house with books. If I want to reread a book, I can just go borrow it again from the library. That said, I do get some of the “Free Friday” books.
