Anyone who's ever owned an Altec Lansing iPod speaker dock will know that they make good quality product. The inMotion Classic III is the third Altec Lansing dock I've owned, after the original inMotion nearly a decade ago and more recently the
Altec Lansing T612 - High End Speaker For iPhone/iPod - Black, which is still in use as the main stereo in our home. Both were/are excellent products and the inMotion Classic III continues that trend.
Sound quality-wise I can't really fault it. Considering its size and intended purpose it provides clear playback. If you're an audio snob who wants to hear every note of a performance then maybe you'll be disappointed, but if you were I doubt you'd you be listening to an iPod in the first place. If all you want to do is fill a room or space with sound then the inMotion Classic III will happily do that for you.
Looks wise its also pretty good, if hardly striking. For the most part matt black and with a long but relatively shallow profile it seems intended to blend into the background rather than be a stand-out piece of cutting edge design. It functional rather than flash.
This is best epitomised by two nice little design features; the pop out dock and the magnetic cubby-hole for the remote-control. The former has two advantages. Firstly it prevents you from accidentally damaging the iPod connector when the dock is in transit and secondly it means that you don't get a build up of dust and dirt around the dock when its not in use (something all my various iPod docks have been prone to). The remote control storage is even better however, as it improves the portability of the entire device.
The same can be said of the inclusion of a built-in rechargeable lithium battery in the Dock. This is probably the unit's most user friendly feature, as it allows you to simply unplug the unit from its power cable and carry it to wherever you want without worrying about whether you have the correct batteries for it. The one thing I can't say is how long the battery lasts after a full charge because I haven't had the unit long enough to run it down, but if its anything like a typical mobile phone battery it should allow for several hours of playback.
If there is a downside to the unit (beyond its somewhat pedestrian appearance) its one of size and weight. Prior to getting hold of the inMotion Classic III the portable dock I used when travelling was the
JBL On Stage Micro Black Mac/Win. Whilst that unit lacks the built-in battery, remote control cubby-hole or retractable dock it is lighter and smaller than the Altec Lansing, which is important when you want to stash it in your luggage. The Altec Lansing has features that make more suitable for carrying around with you, but its size and weight definitely count against it and reduce it from five to four stars.
