My opinion is that the device is very well done, the screen is sharper and higher resolution than the Kindle, and of course has color.
I know it is heavier but for anyone that reads Vollman or Pynchon type books then it is actually a weight reduction, for paperback readers it might be a shock, except that I'm carrying access to over 30,000 books for free and many more paid.
I like the keyboard also, it is much easier to use than my iPhone, the larger layout makes it fine as an email, short message machine.
My Netflix account connected directly and the streaming video is very cool, when you pause a show, upon returning even a day later it begins streaming where you left off.
The video quality is stunning, I've shown dozens of people and they all comment on that feature regardless is they are hung up on Multi-tasking ( a term that most people don't even understand or they wouldn't really expect it on a device like the iPad), USB connection (mine is connected into the USB port on the MacBook right now), and the inability to run Flash ( which is a pile of garbage code that has outlived its usefulness based on the amount of problems it causes on desk tops).
The Star Walk App is awesome, as is the Bloomberg, Good Reader and Elements.
The touch screen is greatly improved, and with the larger size uses 1,2, and 3 finger taps to greatly expand the touch screen capabilities, look for more about this in newer apps.
Many of the users are stuck in computer mode or iPhone/Touch mind sets, that is the wrong way to think about it, if you feel that way wait a while and others will expose the way it is best used and then you can decide if you want one.
