Flashed. Only 40% memory in use at boot -- very nice. Glad to see the taskbar data connection cleaned up.
The haptic feedback when typing on the hardware keyboard isn't really my thing. I'm a fast typer and it goes nuts. I would assume haptic on the actual keyboard is a bug considering you already get haptic (aka sense of touch) in real life when using the keys.
Seems super fast. Happy so far! Oh and I also got the sim card setup at boot. I'm sure nrgz will fix that on the final release though.
