^ Indeed, good points all IMO, especially re: the cons of cloud storage. Still, in my case, as much as I value my privacy, I am prepared give a wee bit in exchange for the access convenience and redundancy.
Disagree on wifi being required though. I connect my Kindle to multiple PCs/laptops via USB and grab my stuff that way, so only need web access in general. Yes, I have a Wifi device, so in my case, whatever I choose at the moment is fine.
