SIRIUS XM will not put the R & D into a new portable satellite radio without making it dual band capable. Simply not worth it, IMO.
Based on their "divorce" from the Stiletto designer/maker, the next portable satellite radio will be:
- like the XMp3 (screen quality, menus)
- like the Stiletto (wifi enabled)
- like an iPod nano (built in 8-16gb+ of memory...only some of which can be used for SIRIUS XM content, though...damn RIAA)
- Dual band (able to subscribe to SIRIUS, XM, or both)
At least, this is my wishlist...
