Altec Lansing Orbit portable MP3/iPod speaker review

Haven't posted a proper review on this blog before, but having just returned from a week's holiday with a particularly awesome gadget, feel compelled to do so.
Just to be clear, this is a review for the older Altec Lansing Orbit portable speaker, not the iMT237 - the newer, chunkier model has recently been featured on the Gadget Show and Something for the Weekend, gaining extremely positive reviews both times. I looked into that, but the higher cost, and Tonka-truck looks put me off, especially when I saw this older, sexier model:
I picked it up for £17 through an Amazon marketplace seller, and was thrilled to receive a product that felt as durable and simple as a travel/portable speaker should. I've owned and used other speakers, but this is the first to completely forgo overly clever (i.e. unnecessary) functionality for pure speaker-goodness. It's a speaker, that's it. It won't charge your phone, dock your iPod or walk your dog, it amplifies sound without the need for mains electric and does it bloody well.

Like all the best gadgets, it came complete with batteries (3 x AAA) so I could immediately plug it in and try it out, and it rocks. Hip hop, folk, episodes of Family Guy, they all sound awesome - like no other similar portable speaker I've tried. It can go loud if you want it to, but the quality is such that you don't need to whack up the volume just to hear all parts of the sound - for the past seven days I've been running this in a large outdoor space and never had it above 75% volume on the iPhone.

Apart from the sound, the simplicity of the design and reassuring weight of the speaker means that you won't worry about it being a permanent fixture in your laptop bag, meaning it could double up a presentation aid as much as a music/film speaker. Super.

The only niggle is the on/off switch; basically the whole face turns about 5mm, which should be a nice extension of the simple build, but actually feels a bit gritty and tough to do without using two hands and some brute force.

So, there we go, hopefully someone will read this and find it useful.

ps. I am not in any way connected with Altec, this gushing review is all of my own doing - if however one of you clever Altec peeps reads this, let me know what you think.
