Depends on your style of backpacking. If you do long miles each day, there really is not a lot of boring tent time. If on the other hand, you stop at 2-3 in the afternoon you have a lot of time on your hands. My "entertainment" then is fishing. I may fish the daylight hours and then cook dinner in the dark, with a lamp (I like the small Luci solar lantern at 3 oz). As for inside tent, I have a 1-oz I-pod that I use for music or books on tape. It has about 8-10 hours battery life, so on a 9-day trip I can do about an hour a night.

I seem to have my days filled, either with walking, fishing, photographing, camp chores or exploring that I really do not have much need for in-tent entertainment. I also have no problem sleeping 9-10 hours. I do not need to have constant activity or mental stimulation. I guess that is more charteristic of we old folks who grew up without all the current entertainment and spent a lot of time just sitting in the woods contemplating life.
