Well, Guys, I hate to break it to you but, I am the commenter and actually own a 770. The pics aren't great because they are hand drawn (and an artist I am not).
Now let me break some bad news, and good news, to you.
First, the screen resolution is not as great as everyone might want to believe. It is the plain truth. Sure, it is better than any PDA that I have ever owned (and I have owned a lot of 'em), or possibly have seen, but IMHO the PSP has a sharper screen, althought it may not be able to match the 770 technically.
Now the good news, the 770 flat out beats the pants off of any PDA that I have ever owned, including my clam-shell Clie UX-50. The 770, from an operational perspective beats the pants off any PDA period.
Give the review process a chance. The thing to remember about the particular review that I am conducting is that one can only put so much on the screen. This particular review is being done with a very large crayon and you are always welcome to rebut in a well written comment. I would suggest you stay tuned to the review as the "meat and tatters" of it are in posts to come. Trust me, the majority of it is all good news.
