Much as I'd like a good dictionary on my 500, I don't see how it is practical without a Search feature.
Both the old Rocket eBook and the Kindle have this feature, so a dictionary or an encyclopedia would be great. Pity Sony didn't think of this.
The Rocked eBook also had a built-in dictionary, so highlighting a word resulted in seeing the definition. Unfortunately, whenever I came across an arcane word that I did not know, their dictionary did not know it either, alas.
