I don't think most witnesses have the answer for questions such as communication, travel, etc. A common answer would be that it will be left in Jehovah's hands, and He will provide. This thought pattern is rather common among the witnesses, and that is to allow others to do the actual thinking, so they don't have to. For some, it overwhelmes them, so they welcome someone else making the decisions.
I grew up as a witness, and was one until my mid twenties. I never gave the paradise much thought, and if you were to ask me, I actually enjoyed life like it is now. I enjoy what man has made on the earth, and to have a lot of that gone, yes, I agree, life could be very boring.
I like cars, airplanes, movies, music, and many other things that some teach will not exist. I for one, would not want to listen to songs from the songbook forever, with nothing else.
I think it makes much more sense to believe that this is a stepping stone for what God has in mind for us. I don't think heaven is just sitting around with wings on. I think there is an entire universe waiting to be explored, and I think that just might be part of what heaven is. Forever to explore everything.
