After trying out the Galaxy Tab, the Xyboard 8.2, & Sony Tablet S in recent days, I finally settled on this new tablet...and so far I couldn't be happier with my choice.
The resolution is 1024 x 768, so *not* widescreen like every other android tablet out there. The tablets weight is listed as +16oz, however, its ipad-esque form factor really doesn't feel at all heavy. Holding the tablet one-handed in either landscape or portrait is equally comfortable.
Obviously the dpi isn't as high or crisp as other tablets, nevertheless the overall quality of the screen--in terms of viewing angles, uniformity of the backlighting, etc.--is superb. It's much better than the Xyboard and on par with the Sony Tablet S.
I can't speak to benchmarks or 3d gaming performance. However, in everyday multi-tabbed web browsing, ebook reading, music & video playing/streaming, the dual core 1.5ghz snapdragon runs everything smoothly with no lagginess.
Its pretty much stock Honeycomb with custom-designed back, home, and recent app buttons in the status bar along with an aesthetically-pleasing custom font for the tray clock. Bloatware is 'average', a lot of AT&T specific apps, a few games, and a couple of pantech created apps.
Haptic feedback is not something I ever use in smartphones & tablets, so I disabled it right way. Likewise, no idea if the waterproof claims are accurate and hopefully will never need to find out.
So yeah quick conclusion: pantech's first go at a tablet = good. Hopefully the company properly supports the device and comes out with timely updates, if needed, + upgrades it to ICS soon.
