Ironically, LauncherPro is actually writing their next major version from scratch using all kinds of new tricks and techniques that they've learned along the way while working on these previous versions. Up until now, they've basically taken the Google Launcher source code and then forked it off and tweaked it up and down to make a whole new Launcher replacement that, I think anyway, it far better and far more configurable. They seem to promise an incredibly far better Launcher replacement for their next major release--all while continuing to parallel develop in the current version to keep supporting it.

...AND THEY MAKE MONEY FROM IT! Open.. AND profitable.

PS - I forgot to mention one of my favorite features--RESIZABLE WIDGETS! Yep! You can take any desktop widget and resize it as you see fit. ANY widget. If it's a resizing-aware widget, even better.. but for those widgets that don't know anything about being resized, in my experience, it seems to work pretty reasonably well and I've almost never seen a widget get mangled by it. This bodes VERY well for something huge like the Tab--where I might just want to be able to resize widgets to make them just plain look "right" on such a larger screen. I reeeeally like LauncherPro.
