Hi, I'm looking for a portable speaker solution, mostly for indoor use, but would probably take it outside for BBQ's, etc. I am basically between the Logitech mm50 and Altec-Lansing iM7, and I was wondering if anyone has tried both. Right now, the mm50 wins for convenient, compact size, better price. The iM7 is bigger, heavier, would require the purchase of (rechargeable) D batteries (which is both a pro and a con), and I'm assuming it's louder. So, any input as to relative volume, sound quality, build quality etc? Thanks.
