I found my PRS350 because I was looking for an E-reader, and Initially I was torn between the PRS300 and the Kindle 3. But I was looking for info on which one was better so I went looking for an e-book forum and MobileRead was the first place I found.
So I asked which E-reader was better, and was told that either was a good choice. So I bought me a Kindle and then unknown to me a family member had bought me a PRS350 as a belated Christmas gift.
And now I have gifted my Kindle someone in my household, and am carrying on in a passionate affair with my PRS350.
