Today Sirius is unveiling the long-awaited sequel to their innovative portable player, the Stiletto.

The creatively name Stiletto 2 (I had gone for the Stiletwo or the Biletto, but that's just me) is smaller and lighter than its predecessor, weighing in at 4.3 oz, and includes a handful of promising features. Like the Stiletto the first, the Stiletto 2 receives live Sirius programs on the go. The new model also boasts "enhanced wi-fi capability," making it possible to tap into more content at home or around hotspots. The device also features a microSD slot, improved MP3 and WMA management, and the ability to "bookmark" and purchase tracks via compatible online music stores.

A "Love" button lets users store their favorite songs to the device, from radio streams, while scheduled recordings make it possible to capture up and store up to 100 hours of music.

The Stiletto 2 will be bundled with high-quality headphones manufactured by Altec-Lansing. The AHP202SIR antenna headphones feature 30mm drivers, an adjustable headband, and just generally sound a heck of a lot better than the Cracker Jack toys bundled with the iPod and most of DAPs.

The Stiletto 2 will be available this Fall, along with a vehicle and home kit (both $49.99), and an "executive system" (at $149.99).
