No. Much worse. Think 30 seconds for a 7-color display. (B&w can do under one second)

This is outdated and only true for older ACeP displays. The Gallery 3 screen can refresh fast enough (~1.5sec) to be usable in an e-note with color:

And since it's true multi-color, it can refresh even faster by simply disabling the colors and refreshing in B&W (very slightly slower than monochrome screens though).
