Picked this up from Radio Shack as a novelty item.  The phone is thin, but the call quality is quite poor.  Virgin Mobile uses Sprint's PCS network, and Sprint is my primary provider (I have a new Sanyo M1 phone), and the call quality difference is huge.  The keypad is also uncomfortable to use, like many ultra-thin phones -- just not designed for normal human beings IMHO.  Finally, VM's prepaid rate is just too high.  Coupled with limited coverage, I'd say VM's service is a bad deal.
