You can dock your iPad in speakers, just as you would an iPod with a new speaker dock from iLuv.
The iLuv iMM747 can be adjusted to cradle an iPad, iPod or iPhone. It delivers room-filling sound via two speakers and a subwoofer. The tablet top dock will be available early this month at $150 at www.i-luv.com.
