Handheld computers - what is available?

["Oliver Elphick" <olly@lfix.co.uk>]

I have a customer who runs a van distribution system.

He wants his drivers to use handheld computers or barcode readers
when they visit shops, to pick up the list of items needing to
be replenished.  He then wants to print a delivery note on the
spot for the customer and transmit the details by modem, for the
main office to print and despatch the invoice and update the
central database.

What Linux-capable handhelds are available that would be
suitable for this job?
