Or when it's taxing or landing?

I don't understand how a majority of these devices would interfere at all. One way radios, GPS recievers, laptops w/o wireless, PSPs, etc, etc don't send OUT any signals, so why do we have to turn them off?

Even cell phones that send and recieve, don't they operate at different frequencies from aircraft communications? And isn't the plane already being bombarded with tons of cell phone (broadcast) siganls from outside the plane?

What's going to happen if I secretly turn on my cell-phone, and take a call while the fight attendent isn't looking?

I have a Sonicare toothbrush that died and I have cracked it open and am replacing the batteries in it. The originals were AA Ni-Cads but I would rather replace them with litiums. Will any lithium AA's do it or do I need specifically rechargeables? Anyone see any problem with replacing Ni_cads with litiums? Is it safe to assume the charging mechanism in the toothbrush or the batteries will regulate the charging? Thanks.
