I currently have 4 (yes 4) Kindles.
1) My beloved paperwhite, for when I just want to read.
2) Benton, a Fire I thought had died. A guy on e-bay fixed him for $20. He has all my videos. Is running out of memory.
3) Stanley, the Fire I purchased before I found out Benton could be fixed inexpensively.
He carries all my audiobooks, but only has less than 15% memory left.
4) Diefenbaker, less than 2 weeks old, and is amazing. He happily is picking up everything the others can't handle. He also does my audiobooks.
Things will be cleaned up and re-arranged soon, opening up space on each of them.
Kindles aren't tablets, but I LOVE being able to organize their contents, and being able at a glance at the covers (Red, Blue, Black, Purple) what exactly they contain.
I'm weird that way.
At less than $100 each, bought over several years, I'm happy with them. The only problem I've had was the battery port on Benton. Again, he was fixed on e-bay for $20. Well worth not trying to recreate him on a new one.
