There are a lot of iPod/iPhone speaker systems out there that leave your device sitting in the dock vertically. That may be fine for the iPod Classic, but when you're dealing with an iPod Touch, an iPhone, or a fourth-generation iPod Nano, you want to switch into landscape mode to watch video.
Enter the iHome iH41BR. This simple iPod speaker/alarm isn't fancy but it has one key feature: it rotates 90 degrees, which enables you to put your iPod Touch or iPhone in landscape mode and watch movies in their wide-screen format. The little trick here is that the clock rotates as you rotate the speaker and essentially lay it flat on its side. iHome also includes a small remote.
The iH41BR is a relatively small speaker, so you're just not going to get great sound out of it. But the idea is you'd stick it on a bedside table next to you and watch a movie at close range; the speaker puts out ample volume and is fine for casual listening. However, it really does sound like a clock radio--though it's missing the radio. It's also missing GSM shielding, so you'll have to stick your iPhone in airplane mode (turn off the cell radio) to avoid causing interference on the speakers.
To be clear, there are no moving parts or swivel mechanism involved here. You literally just tip the speaker over (there's some rubber pads on the bottom of the speaker that extend around its curved corner). Aside from the alarm basics (sleep/snooze), the only "extra" here is a 3.5mm line-in port, which allows you to use the speaker with external audio sources.
