Portable bluetooth speakers Just picked this little guy up, only 30$ shipped with the points I've earned shopping there. So far I love it. Battery lasts longer than the little jambox I had. Sounds better and goes quite a bit louder before it distorts. I've had my phone in my bedroom, went to the downstairs bathroom and it's still playing fine. That's 2 walls, a solid floor and 2 doors! Do y'all have any experience with the wireless bluetooth speaker systems?
