Scott,
yes the MPP has a footswitch, plus you can physically annotate scores with whatever instructions you want to place on the page,with a stylus or a finger.. you can have look ahead, which shows the start of the next page, you can have a section highlighted, just like using a highlighter pen on real paper, you can place additional notes/ markers/symbols on the staves, you can automatically return to a previous section instead of going forward, in the case of repeats/da capos etc for example. To turn a page is a simple tap on the right side of the screen with a finger anywhere, and the left for going back or use a footpedal. All of score editing tools are post scanning and allow pretty much the same freedoms you have when using a printed sheet..you can transpose a score (as long as its ins the FH format. The MPP is TOTALLY different from laptop in that you can place it on an existing music stand just like a single sheet of music.This is something a laptop cannot do.
I am not extolling the MPP over a laptop or vice-versa, I have used both so I reckon I can give a balanced view of both..They are both excellent tools doing similar things in different ways. As I mentioned in an earlier post, he already has the capability on his E80 to view notation info and turn pages etc etc. If the screen size on the E80 is an issue then there are other alternatives.
