Don't pay a lot of attention to megahertz ratings. Get a unit, test it, and see if it feels fast enough for you. The MobilePro 750C comes with the traditional interface ports, including a Type II PC Card slot, a CompactFlash card slot, a serial port and an IrDA infrared port. It also comes with a VGA port that lets you connect your MobilePro to a video monitor or projector and display color PowerPoint presentations in a larger format. The MobilePro 700 also has this capability and even though the 700 has a monochrome display, it can project color presentations.
Specific details are in the sidebar, but it's worth mentioning a couple features.
MobilePro also comes with ParaGraph's CalliGrapher handwriting recognition software pre-installed. It lets you enter characters with pen strokes on the screen. It's a fine program, but I don't quite understand why, with such a typeable keyboard, NEC chose this particular application to pre-install. I'm a writer and editor, and touch-typing is a basic skill of my trade. But I was touch-typing immediately, almost at full speed.
