New Dell smartphones: Lightning, Thunder, Flash, Smoke

Dell will be coming out with some new smartphones.  According to this story on Engadget, they will be called: Lightning, Thunder, Flash, and Smoke. I wonder if there's a theme here.

Some will run Google Android and others will run Microsoft Windows Phone 7. I wonder who else will enter (or re-enter) the smartphone market here in the United States. Maybe all those companies that used to make PDAs will return. I used to have a PDA made by Toshiba. HP still makes the iPaq and they're still making a few smartphones. Lenovo has smartphones overseas and maybe they'll start marketing some devices here in the US.
