I'm trying to tweak my web and ebook reading experience on the 70bIT to justify the purchase in my mind as an improvement over the 70IT. May still happen, we'll see.
Never really happened, unfortunately. The 70IT is still first in my heart.
Part of the blame lies with Google and Android and the inability to uninstall apps and services I have no intention of ever using. That's just bad.
And the other problem is battery-related. Twice now, I've picked up my tablet to find the battery completely spent and unable to sustain a boot. And I never put it to sleep. I ALWAYS power off. (Okay, ONCE I put it to sleep, but I knew immediately that that happened, and it was my finger's problem, so I woke it up and powered off properly.)
MAYBE I put the thing to sleep ONCE without knowing it, but twice? I doubt it. Powering down is a fairly ingrained habit with me. I love my 70IT too much to take it on the road, but OTOH if I have to charge the 70bIT via USB on the road, heaven help me.
