Shopping for a Calibre-friendly tablet

Hello, friends. Am about to shop for a tablet, and would appreciate it if you could steer me in the right direction.

For reading ordinary text, I'm happy with my Kindle Paperwhite. However, for reading cookbooks—or any publication where one might want a larger screen capable of rendering photos in color—the Paperwhite doesn't cut it.

Everything in my Calibre library looks great on my 15-inch laptop, but I'd sooner keep my laptop out of the kitchen. So I'm considering a tablet. For cookbook reading, a 10-12-inch screen ought to be a good size, and if I can find a tablet for under $400, that would be swell. Then again, I'm willing to spend more for a tablet that won't croak after a year or two.

In choosing a device, the ability to run Calibre (or at least display the contents of its library) is my number one priority. My laptop runs Windows 7, so should I be shopping for Windows tablets? Sorry if that's a dumb question, but I have little experience with operating systems outside of Windows.

Any guidance would be much appreciated.
