If you're seriously considering getting an Ipaq or a Casio, why did you ask how well it runs on a E-115. or that was M-155 is that like a mix of the EM-500 and the E-115
anyway, the E-115 is a lot like playing Quake under a strobe light. If you're that concerned about the frame rate (does it flow nicely?) then get the Ipaq. Hi res movies meaning what exactly? 800x600 vs. 320x240 high res, or 240x176 at 300-400k a second vs. 176x144 at 33k a second? It runs movies fine if you know what you're doing.
