You can still read the books, in an on-line "cloud reader". All you need is an Amazon account. Later, should you get a Kindle, you can then download any books you've purchased to the Kindle. But the base Kindle is only $79 through Amazon.
For someone who has trouble with small print, a kindle is great, since you can adjust the font size to whatever you need.
Thanks. I downloaded the Kindle for PC App to use. Eventually I may get a Kindle.
I can’t recommend the Kindle platform enough. I’m referring to the basic ~100 dollar B&W “electric ink” version, not the color Kindle Fire. The basic Kindle works like a dream, set the font as big as you want, and it runs for WEEKS on a single charge. I don’t even take my charging cable when I’m on a road trip or vacation.
