Ok, I read the engadget review, and I think it's pretty fair.
Nothing really annoyed me except the below which I just feel is pure personal preference coming from a seasoned Android user.
"We also couldn't help but longing for a button or two on each side of the middle gesture area -- sure, we're spoiled by the home, menu, search and back buttons that have become commonplace on Android handsets, but keeping up with the Joneses should probably apply to more than just lake houses and motorcars. We also found it frustrating that we couldn't activate the display with a long-press on the gesture pad; reaching for the power button is awkward at best (the location, that is), and sliding the keyboard out wasn't always preferred."
Missing search button? That's what Just Type is for. Long presses preferred (ugh!) and dn't wan't to press power button to awaken? (I like doing this) Don't want to open the slider? I'm so thankful pre has a slider.
But besides those, I found the article informative and well-written. There are plenty of praises and hopeful words for our ill-fated device too.
