Apple Inc. touched up its line of laptop computers Tuesday with a minimal nod to the economic turmoil that might push consumers to be more frugal this holiday shopping season.

Apple did lower its least expensive laptop, the existing version of the entry-level MacBook, by $100 to $999.

But in the updated versions of its MacBook and MacBook Pro machines, Apple focused mainly on adding features. Some had been in the svelte MacBook Air, including thinner laptop casings and a “multitouch” track pad, which, like the iPhone, understands gestures for spinning and zooming.
