I think I've have to tell her to go around in the stores and feel the different devices her self. If she likes the 5" Opus it comes in pink, and even the Sony PRS-350 is really good looking
On the other hand, Calibre isn't that hard to master and most test crown the kindle 3 to be the best... I can see some advantages in that we have the same device if she needs help over the phone.
Swedish isn't that different to english that i think any E-reader should have any problem. The only letters to differ is the å, ä and ö.
It's a really tough decision...
Please come with more tips on stores in the NYC.
Thanks for the Openoffice tip, but we are already using it in our family. In fact, our entire city community try to use it during the last year. Unfortunately the non-techie city-employees complained so much that they are back to MS word :/
