Few reasons - 1) you will need an analog to mpeg encoder anyways, so you are missing one box if you are replacing that all-in-one access point + mpeg encoder unit. and 2) With the 4 channel encoder I have, I can directly encode 4 cameras, and retain full 480i resolution on each when displayed on an iPad. With the matrix, you only have one 480i output, so you lose some detail when trying to combine 4 cameras. 3) You can configure on the fly how you want to see all the streams on the ipad. Double click on one video, and it does full screen. With the matrix you have to go back to the trailer and configure by pressing buttons on the unit.
