Lithium Ion batteries setting 787's on fire

Lithium ion, stores lots of juice, very high voltage, great batteries.  Boeing used them on the 787 to save weight and space.  Looks like Boeing didn't see that U-Tube video of a laptop bursting into flame right on a conference room table.  Now they have customer's grounding their brand new 787's 'cause the lithium ion batteries are bursting into flame.  Aircrew and passengers take a dim view of in flight fires.
