Plug-in-style MP3 players--that is, those with the USB interface built right in--have been enjoying a bit of a renaissance lately, as evidenced by the recent release of the SanDisk Sansa Express. RCA has now joined the trend with the Pearl, one of three players in the company's new Gem line. Like the Express, the Pearl is also aimed squarely at the budget-conscious, with 1GB and 2GB versions retailing for $39 and $48, respectively.
