The screen orientation was stuck in an upside down position, the buttons on either side of the display were unresponsive, and screen was frozen in a "Connecting…" state in some program I didn't recognize, so all I could really do was pick up the device and look at the hardware.
It felt really nice and solid. The back had a smooth (rubberized?) surface, which I appreciated considering how glossy and slippery the Galaxy Tab can sometimes be.
I didn't have my Tab with me at the time, but the X70 felt comparable despite its thicker profile. The entire face of the device was covered in either glass or hard plastic (just like the Viliv N5), so those are capacitive touch buttons (not hardware buttons). This was evident from the press shots the other day, but I still thought that maybe at least the mouse buttons would have been actual buttons.
I'll spend more time with the device when it's actually functional tomorrow but based on the few minutes I had with it today, it has the potential to be another winner from Viliv.
