I really don't care if the SysRock has a USB port or not. I want my phone with me at all times. I charge it overnight and it usually lasts all day.
I don't understand all this talk about the sound quality. I use the SysRock in my garage shop or maybe the driveway. Usually, I am wearing SensGard hearing protection anyway. Just as I don't like the inconsiderate people that fill up their car while listening to loud bass thumping rap, I don't want to blast my family and neighbors with loud whatever. The sound quality is good enough for what I listen to most, namely talk radio, sports, news, and weather. I will use Bluetooth to listen to Pandora or something else when there is nothing on the radio worth listening to. I am happy with that combination. If I want hi fidelity music, I'll listen to the system in my house.
I am not looking for the SysRock to provide a major advantage over what is already on the market. The SysRock's raison d'être in my opinion is that it uses Festool batteries, small form factor, radio and bluetooth capable when I want something other than radio.
(The SysRock without the case will fit in most systainers even with the tool inside. Wouldn't work with anything bigger.)
