The iMainGo is an iPod case and speaker system in one compact package.

Okay, so this little item is certainly not a world-changer, but I thought it was a great example of a simple idea done right. The iMainGo ($69.95) is a DayPlanner-sized iPod case that houses and protects your iPod, plus connects it to an in-case digital amplifier that powers a surprisingly robust in-case pair of full-range speakers and tuned base-enhancing ports.

Your iPod is cradled in one of the supplied (and cushioned) adapters, and its Click Wheel controls remain accessible - you don't have to open the case to get to your 'Pod's controls. According to an iMainGo spokesperson, at 80 percent volume the case's four AAA batteries should power the device for 30 hours. Oh, and if your iPod's software has an alarm function, the iMainGo can wake you up in the a.m. - or, of course, whenever you choose.

As of today, the iMainGo is available only in black, but nano-inspired colors are on their way soon, Also, unlike many Johnny-come-lately iPod add-ons, the iMainGo works with any iPod every manufactured. Hey 1st Generation 5GB holdouts: Feel the love!
