I bought my wife a Kindle (the new Kindle 4) late last year. Went for the plain vanilla wifi version and it works great. You really don't need 3G. If she wants to download / buy a new book she simply hooks up a wifi hotspot from her phone.
Also, you can email pdfs, word docs etc to your Kindle too.
