It has been a long time since I have been here on MobileRead so forgive me if this topic has been discussed ad nauseum - I did do a search and didn't find anything recent.
I have an older Kindle, the Kindle 3, which still works perfectly; I enjoy reading with it. I am looking into my upgrade options, however - upgraditis strikes again.

The Kindle Paperwhite with WiFi (no ads) is at the top of my list.
Except for the fact that Amazon is no doubt even more intrusive (Cloud control and all, lol) than they were in the days of the Kindle 3, I don't really see any, but are there any serious downsides to going from the Kindle 3 to the newest version of the Paperwhite?
