Thanks for the info and suggestions. The improved screen resolution is interesting, but getting extra storage instead of paying for the add'tl screen size probably is not. I wouldn't get the 4G functionality. I just want to be able to download some few apps, (sideload) mostly books and perhaps a few movies or TV episodes. I can always xfer the movies and delete them as I watch them. I mostly read. Oh, if I have storage space, I will fill it - but it is probably not strictly necessary.
I am borrowing a 7" KFHD for a few weeks and really find the size hopeless, except for reading. Yes, videos and music sound great - but they should also on the larger device. When viewing a webpage or large page PDF, I have to keep on increasing the font size and moving it around to see a whole page - and after a while I get a headache.
I have purchased a SGP5 (5") as a portable personal media player on-the-go (calendar and that sort of thing) device, as I think the 7" would be too large for me to carry around.
I am considering the 8.9" or perhaps a 10" something. I enjoy having lots of words on a page as I read quickly and PDFs display easily. Also, I play bridge and the 7" is a bit too small to display my favorite Bridge site well!
Probably the wise move is to continue to use the 9.7" Kindle DXG, which I really do love reading on, and wait and see. I have a 9" netbook, and 27" monitor to do all the other stuff. I'm just so tempted...
I guess the software versions on the KFHDs are the same? Or doesn't that compare for the Fires?
Thanks for the opinions, you guys are the power-users and have looked at so many devices!
