Thanks for your kind & helpful reply JSWolf !!

I can only respond thusly...
Sometimes (rarely ??) in this life we find our desires met with what can only be called a 'perfect fit'.
For this olde guye, that has manifested via a couple of amazing horses (now passed on), the ideal make/model of car - and an ebook reader that has all that I need & does exactly what I want.

The 6" EzReader is all this for me:
Easy to use single-handed;
Has an easily replaceable battery;
Has a full-sized SD card slot;
Does the file formats I require 100%;
Is -not- tied to any source, site, the internet, or need for wifi.

The Kobo Libra H2O looks nifty - but doesn't tick my boxes - and its $170 price means I'd have to ignore the electric bill for a month in winter...a very silly notion here in Vermont !!

Between the end of the Jetbook & the arrival of the EzReader I tried good, used readers, including a Kobo, a Kindle & a couple of others which got re-sold for all the same reasons posted above - and I actually made a little gain thereby which allowed me to get my reader with its perfect fit.

When (years ago) a reader died on me with all its files onboard, I learned the great value of those plain, old cheapo SD cards - as well as the great utility in having the ability to just plug them into the PC to manage the ebook files on them - and those old SD cards are not only a nice form-factor for handling, but they are also incredibly long lasting. (I detest micrSD...it is just too doggone small !!).

A favourite bit of wisdom that I try to abide by:
'Don't fix it if it ain't broke.'

Thanks Again, and Best Wishes.
