"The unprecedented sales success of the Apple iPod portable music player has spawned a growing peripherals business to supply the owner base with a wide range of accessories. Among the most popular add-ons are compact portable speaker systems which allow the user to un-tether from his/her headphones and share their music with others. Altec-Lansing, in particular, has had great success with a variety of portable speaker systems, from the ground-breaking inMotion to the subsequent IM3 and IM4. Now Logitech has entered the fray with their mm22 Portable Speakers."
