I'd love to give honeycomb a try for sure, but after a little sniffing around I've found out:
a) that there's no indication of any nature whatsoever from Samsung that they intend on releasing Honeycomb for the original Galaxy Tab; and
b) that it would entail giving up my tab's phone capabilities (barring a fix by android, of course);
Can't speak for the rest of you, but I do use my tab as a back-up phone. That, coupled with having 3g connectivity wherever I go is a huge bonus and I'm pretty sure I would not like to give that up. What I would like is a nice cold ice cream sandwich sometime in the near future...
