It looks like those folks jonesing to get their portable Sirius on are going to have to wait just a little bit longer, as the satellite radio giant has apparently asked all of its retail partners to suspend pre-orders on the Stiletto 100 until further notice. The TSS Radio e-tail site where the information first appeared claims that they "still expect the Stiletto near the end of September / early October," although another authorized retailer, Crutchfield, has taken down its pre-order page altogether. So far no one seems to know exactly why Sirius made this move at such a late date, but aside from supply problems (which are unlikely), the major contender for the delay would seem to be our old friends over at the RIAA. What's strange about this scenario is that unlike rival XM -- which is still battling the record labels over licensing fees for their portable players / recorders -- Sirius seems to have made nice with the recording industry following the little brouhaha over its dockable S50 player. Bottom line is that we don't like a mystery, so we're gonna poke around a little more and see if we can get to the bottom of this unexpected development -- meanwhile, it's SiriuCE or bust for live, pocketable (albeit crappy) Sirius content until further notice.
