Mark, the display size of these tablets is described as the diagonal distance from the top left corner to the bottom right. So, both are considered to be 13.3 inch tablets. They are a little narrower and taller than the MusicPad Pro in the portrait position.

I think that anyone who needs to use a foot switch to turn pages should avoid the Archos. Other than that, there is not a lot of difference for music display except for battery life. If you are just looking for a place to store a lot of PDF sheets or books for reference, it would seem that the Archos would be the most economical choice.

The MobileSheets application works quickly and dependably in both tablets for lead sheet display. The Archos works fine for me but I keep almost all of my songs on a single sheet each and don't use a foot switch. I think it is an incredible bargain if no footswitch is needed. If cost is of no concern and if you have good vision, an iPad may be a better choice. The iPad is just too small for me.
