Apologies if there is a similar thread currently active, but I searched back seven pages and did a search and nothing came up.

As the title implies, I'm considering buying an Ebook reader soon, and I'm wondering if anyone has any recommendations. I have almost no interest in using this device for anything other than reading large amounts of text for long periods of time, so keep that in mind.

Primarily I'm concerned about four things:

Eye strain
Battery life
Cost
Flexibility when uploading files from my computer (Basically, how difficult would it be to read FF on it.)

After doing some light browsing, the Kindle Wi-Fi seems like the best option, but it's sometimes hard to wade through the bullshit add campaigning, so if anyone has specific experience with it, that would be especially helpful. I doubt I'll ever purchase a book while away from the house, so 3G isn't really needed.

So yeah, basically it boils down to, "Is there a better option than the Kindle Wi-Fi?"

Thanks in advance.
