There are 3 new iRiver devices that are being shown this week at CES which use Flash Lite and here are some brief details.
iRiver Spinn: Flash memory based PMP device with a 3.2" 480x272 screen and DMB support. Flash Lite UI.

iRiver IAmoled Photo Tank: HDD based PMP with a 4.1" AMOLED screen. Flash Lite UI.

iRiver Wing: Flash memory based Windows CE Pro OS with WiFi and QWERTY keyboard. Flash Lite support.

Once I have more information about the implementation of Flash Lite for these devices and what it may mean for developers I'll post it.
