As of v3.1.10, I can no longer recommend Zeam for use on Honeycomb. On my GTab 10.1 at least, it loaded okay but had problems. It would intermittently freeze up when returning to the home screen, or sometimes even freeze homescreen widgets (e.g., Gallery slideshow). After ~ 10 seconds, it would resume and act normally for awhile. Fortunately, I had a backup of v3.1.9, and reverted to it. Now everything works fine once again. So, if you want to try Zeam, use versions 3.1.7 thru 3.1.9 (the only ones I have experience with... earlier versions may also work). I should add that 3.1.10 is not a total bummer, it just doesn't work well on my tablet. I have it installed on my phone though and it's fine.
I also tried Go Launcher EX, which is what started this thread long ago. It has a lot going for it, but in the end, I uninstalled it in favor of Zeam's responsiveness and speed.
