RE: Hand held Barcode scanner - For Picking

The YesTablet seems very efficient, I especially like their stand, 
extremely efficient
for standing users.  We've had much difficulty housing traditional 
computers in cabinets
that don't cramp users or the workflow.

There is also the XP tablet option, especially if you need more 
capabilities with respect to windows.

A great example is:  http://global.acer.com/products/tablet_pc/tmc100.htm

So if you want something more than terminal/WinCE, take a look.
It has built in WI-FI
Especially good for mobile supervisors.
Price competitive, starting at just over $1100.

I acquired on for someone, very easy to configure & use, surprisingly 
powerful.
Just not sure about the durability, that maybe the only issue for the 
shop.
