I like this one.
The screen does look larger because of the numeric keys above. And they slide out keyboard is larger because it doesn't have the D1 square scroll on the side, it has the arrows. I like the larger keys: return arrow, shift, alt. That will help a lot for me. I never used the tab key but there's a dedicated one (instead of with the alt) on here. Great keyboard, I'd say.
I don't use my keyboard much, and like SnydersWeb said, auto correct would help there. But I do use it and for longer texts or multiple texts, e-mails, blog, etc., it helps with data entry.
I hope it has HDMI out. I had to buy a new tv and dvd player and both have HDMI ports, so that would work great.
It does look thinner then my D1.
