A MID gives you full internet capability and meda functionality in a device just slightly bigger than the average Pocket PC. the lack of a phone radio is the only missing ingredient from making this a full blown smart phone but other than that it has complete connectivity in blue tooth and wifi. MIDs usually have a very high resolution screen for optimal internet browsing and media playback.
Seems like this will be the new trend on the rise this year...
