Of you who have used cell phones exclusively to land phone, what is your opinion of this experience?

Drawbacks to cell phone only? Advantages? Do you plan on continuing phone service with only cellular? Would you recommend giving up a land phone to use only a cellular? One reason I shy away from it is that I never can find my cellular when I want it, or can't get to it in time. Another reason is that I tend to let the battery go down accidentally. Is this a problem with you, too?
