[Braillenote] BN and PK durability

[beth]

Jonathan, on another list, it was mentioned that laptops are pretty
fragile and, if they are bumped even slightly, even when in a case, they can
go squirrely.  They also last for about two years, on average, with hard
use.  Is this true of the BN?  I know you said in your ACB Radio demo that
the PK is rock solid.  Thanks.  Beth
