I rooted and installed a custom ROM on my KF1, and while it made it a much better tablet, I regretted the loss of the Amazon ecosystem that the KF is really made for.
I love my KF2 and will not be rooting it. I have a rooted Android cell phone and a Nexus 7 if I want an open Android tablet. But I find I use the KF2 a lot - in the stock configuration - and specifically for easy access to the Amazon content it was made to deliver.
IMO, if you want a non KF tablet, go buy one. There's a ton on the market, and many are quite good and inexpensive.
You get a KF to access Amazon content.
That's the obvious choice, and I'm happy with my stock KF2 as is.
