Themes
Some cool themes are standard, the eye is one of the "live wallpapers", you can also choose from grass that sways in the wind, this crazy oort cloud looking thing in your choice of colors, a slowly spinning spiral galaxy, a few audio sensitive live wallpapers (These also cam as options on my partner's incredible)... and then you have the traditional static wallpapers, most of them are industrial in the droid theme, and kinda cylonish... and of course you can set any picture as the wallpaper.
As for the vibrate... its definitely more solid and compact feeling than my Storm 1, if that makes any sense, very similar to the incredible, and closer to the IPhone than my storm was... my storm was pretty fierce, you felt it on the table... the X isnt quite that strong, but certainly not "anemic".
