The lucky folks at CNET got to manhandle the forthcoming Slacker player while at the SXSW music fest. The player, which will have built-in Wi-Fi and the ability to sync with your personalized Slacker service, looks pretty fat and big for a flash player. CNET also reports that the battery on the final unit will most likely not be removable. The good news is that the player will have an SD card slot for bumping up storage capacity and the interface is pretty straightforward. The coolest part, however, is that the Slacker folks are talking with other DAP manufacturers so there there may be a chance that you'll be able to listen to your Slacker tunes on non-Slacker portables. You hearing that, iPod?
