I was actually considering this, when the specs were revealed first, but £500 tablet that's laggy out of the box? no thanks.
I also don't feel like browsing XDA and flash custom ROMs every other day, those days are gone. I just want to root the device and not care anymore.
Nexus 10 v2 is the main candidate now. still using HP Touchpad, but it's showing its age.
I don't blame you.
With KNOX/E-Fuse, ghastly + laggy Touchwiz I'm bailing as well
