SIRIUS satellite radio is slowly catching up to its competitor XM, but they're gaining ground. Yesterday the company announced Target would carry its XTR1 "Stream Jockey" receiver. The palm sized radio can by used in the car or home and goes for $149. Target will also sell a boom box that fits the XTR1 and you even get a $25 gift card with purchase. The press release doesn't say if you can use that $25 to pay the first two months of the $12.95 SIRIUS subscription though.
