When I first saw the screen shots, I though, meh, too much screen space used up for the returns.  But I downloaded it and gave it shot anyway.  I still do not like how  much screen space is taken up by the dividers, however, this thing is FAST!  Very impressive.  The web browser is pretty good in that you get a quick preview before the page loads.  Now I do not know if this is a diff web browser or safari re skinned.  My impression was is that its an integrated browser, but I thought Apple did not allow other browsers on its OS.  I have not found anything on this yet.  As a browser, its seems ok.

Its a free app, so download it and play with it for a bit.  I plan to.
