From time to time a poster here (and in other places) will say that Kobo could "turn on" the feature within Adobe ADE that would support both the Adept version of DRM that Kobo, Google, Sony and others use and the DRM scheme used by Nook. I have no idea if that is true or not. I do know that right now, only Adept DRM (and Kobo's proprietary kepub drm) can be used on the Kobo.
Rumour has it that there are tools available that will remove the Nook DRM so that you can sideload the books using drag and drop or a program like Calibre.
The search feature on the Kobo site is still not very good. It helps to put your search terms within quotes. I tend to use Google for search and append the work Kobo to the search term. The links are almost always good, either returning a link to the book on the kobobooks.com site or a page that tells me that it is not available in my region.
For spelling, right click on the word, and choose add to dictionary. Problem solved.
