If you have digital manometers or electronics, you most likely need a PC or Pocket PC to operate it. Desk top PCs can be cumbersome and Laptops can be akward too.
I just received a Fujitsu Tablet PC from J&K Sales for $125.00 including a docking station for all the ports (serial, printer, monitor, keyboard, mouse). This is the Stylistic LT and is a Petium 266 running Windows 98se.
You can operate a Tablet PC without a keyboard or Mouse by using the touch screen and a stylus.
I will set it up and give a reveiw and some pics maybe this weekend.
Here is a good pic of a similar model (much faster and more expensive).
