agreed, I'm looking for info as well on bad apps
I'll throw a few out there...
there is nothing harmful or malicious (spelling? sorry) -- however, I'm not a big fan of a lot of the home replacement apps. I've had bad luck with Panda, dxhome, and Helix -- they cause system slowdowns and lots of force closes.
I HAVE had success with LauncherPro. I also tried adw and no love there.
so.... try to be happy with the stock home launcher to avoid getting hooked oin the launcher apps and settling for decreased speed. (just my 2 cents)
