One of the great things about Android is that no matter what kind of custom user interface, overlay, or skin a manufacturer preloads onto its devices, it can always be changed and in some cases permanently removed.
Flashing a custom ROM is an effective way to do this, as most ROMs include their own themed launchers and some don't include the manufacturer's skin at all, but one of the many third-party home replacement apps from the Market and elsewhere can offer a quick fix too. Root isn't required for the latter option, which means that every Dell Streak user (regardless of their familiarity with DJ_Steve) can use something other than the less-than-well-received Stage UI as their default launcher.
So what do you use on your Streak? Cast your vote in the poll below.
LauncherPro and ADW.Launcher are two of the most popular home replacements, but there are other fine choices out there too. Some of you may still even be using Stage, and that's fine too. Use what you like and what works best for you.
I use ADW.Launcher on my Streak and Streak 7 simply because I don't like Stage (reasons: not a fan of the widgets and too much wasted space on the sides). I didn't spend much time checking out and comparing all the different launcher alternative; I just happened to install ADW first and I liked it enough to stick with it.
