Looking for an affordable PMP? Check out the mTrix, a clamshell designed PMP with a 2-inch LCD screen. It supports MP3, WMA, WAV, ASF, AVI/MOV, along with JPEG. USB 2.0, clock, calendar, support for nine languages, and a rechargeable lithium ion battery are some of the other features. It only comes with 32MB of flash memory, but there are SD/MMC slots so you can increase the memory if needed.
