"The DIAD V's full specifications are roughly comparable to a low-end smartphone, with a 1GHz processor and 1GB of internal storage (expandable to 32GB with Micro SD.) Still, given that the last update was over five years ago, that's a big jump from the 400MHz processor and 128MB of memory on the DIAD IV. It's also moved from the Windows CE operating system to Windows Embedded Handheld 6.5."

About 100,000 DIAD V's were deployed to the field.

Although not about the DIAD V, this is an interesting read on DIAD IV. Technology is not cheap ($22M to develop DIAD IV and DIAD III cost $100M) but the positive is that generally speaking, overall costs will continue to be driven down as new technology emerges and much of the technology infrastructure is already built.
"Atlanta-based UPS spent $22 million to develop the DIAD IV, which will be used by 70,000 drivers worldwide, according to spokeswoman Donna Barrett."
