If you don't know all about Unitech and their amazing product line, you really should. We teamed up with Unitech when we were asked by a client to develop Mobile Sales Force software for them.
We didn't buy the Unitech PA600 ruggedized handheld mobile scanner / PDA because of the price (even though it's reasonable), we ended up using them because we arranged a field-test of Symbol's (now Motorola) MC50, MC35 and MC70 scanners, Intermec scanners and all the other "big boys" as well.
Out of all the devices, our client liked how the Unitech PA600s scanned and held above and beyond everything else.
