Minirig - portable speaker

I've only just started thinking about connecting my iDevices to an external speaker for a more portable setup - like partying outside somewhere.  This little unit looks like a decent choice;

It's the MiniRig MR115 portable loudspeaker.  It's rechargable by USB (1 charge lasting 50 hours!) with 15W output and a quality 3" driver.

Full details can be found here.  They are priced at £85 shipped from the UK.

I've just ordered one, so I'll let you know how it goes with an iPad & iPod Touch!

*UPDATE* - The MiniRig arrived this morning, excellent build quality and superb sound - amazing given it's small size.  I can plug this into the iPad directly and have a mobile party immediately!  I'm also going to be using it with my Tenori-On and OP-1...but only when everyone's out of the house!
