They are much larger than the average data collector. The screen area is about 10"x12"". (I think it's about 9 pounds. Bout the same their hunting rifle weighs, so they can't fuss much.) It comes with straps that you can use to either hang it on yer belly or wear it on a forearm. Most of the guys are using tripod adaptors they have made or are using the small plane tables. The power in the field is such that they haven't had time to really complain about the size and weight.They say it's really easier than juggling a data collector and a field book. (The field book is maintained in the unit in a journal file.) They even maintain their time sheets on the unit and submit them daily via our server. Any control data they may need in the field can be directly accessed from the web sites using the WIFI stuff.
There is an onscreen keyboard that works with a stylus. A wireless keyboard and mouse can also be used with no real problems. Everything is wireless and there are several Bluetooth features available. There are no wires linking the data collector to the instruments. They are supposed to have a 90' range, but 30' in the woods is more realistic.
There were a lot of raised eyebrows when we first started this project. The old time field hands were resistant. That lasted about a week. Now you couldn't separate these guys from the tablets with a crowbar. Like any new technology there are growing pains, but now the field hands are as rabid about these things as I used to be about R14.
Be aware though that the posted link is not quite true on their "Ruggedness". We had 2 of the earlier units shut down due to the Mississippi heat and humidity. That may be pretty much fixed now.
You cannot drop them on concrete as they state. One of the guys gropped his on our carpet in the office and the screen shattered.(Understand our carpet is that cheap, commercial, syrveyoirs can walk on it with muddy boots, "plush" pile. Not much protection there. But is is REALLY good for building up a static charge on a cold winter day so you can pop the crap out of the guy in the next cubby.)
Also ment to mention that we get the "enhanced screen". Tha base unit is made to be used generally as an inventory device, so it's screen works well in a warehouce environment. Our screens are clearly visible out in the Mississippi sun. (I wish I had a screen like this on my cell phone or digital; camera, both of which are useless outside on one of our sun drenched days.)
