"Biggest issues: SLOWness and Spontaneous Reboots!"2.0 starson by EmbeddedSwEngineer
Pros: Performs basics of purchase, download and reading a few books very well.
Cons: When loaded it behaves like Windows ME (remember?). SLOW. I mean maybe a 5 minute wait! SPONTANEOUS REBOOTS may take even longer to complete! Even when all you did was hit the page button.
Summary: Best practices in software engineering have obviously not been followed. No thought has been given to user ease, as seen in such things as inability to easily sort by collections; meaning of the word collection differs across websites, devices and apps. NO systems engineering has been done to make all these applications perform cohesively as a product family. I.e., written and thoroughly reviewed product and software requirements specifications. Thorough system testing with a loaded up device would have detected all the above mentioned issues.
If you will have many books, I suggest getting an iPad for your Kindle books. Then get a Kindle for reading in the sun, but don't load it up.
My biggest suggestion is to Amazon:
FIRE ALL YOUR SOFTWARE TEAMS, TOP TO BOTTOM.
Especially at the top; however, a good team would have made these products successful IN SPITE of MANAGEMENT. Hire American contractors, from Director of Software Engineering, on down.
