Too much for this device.
Tried this ROM and it was really REALLY laggy off the bat. Made sure it was OC'd, performance selected, and completely disabled animations with the usual de-krufting of useless-for-kindle apps/gapps. It's still unusable. Hit a button and wait 10-20 seconds for a response. And I made sure to flash it right and wipe what needed it.
Actually, I found KitKat ROMs to be mostly overwhelming for this old hardware, and wondered why so many wanted lollipop given that (not sure if there is such a thing as a fast otterx rom though). Might just go back to ICS or a nice JB rom with tablet view, heh.
But the OTA updates almost made me want to keep this. That is some cool stuff. Also, off-topic, waiting to see how Lollipop pans out on the TF201.
