What is worse, was there was an instance wherein a string of orders have been printed out by the receipt printer, but was missing in the database! (Only the Sales header was saved, the child details went missing).

Cannot comment on the touch part, but vfp can be workable on Atom and 1 GB can be usable if the OS does not have to handle too many other tasks.

32GB sounds borderline (if the OS is on same disk). You did not specify the Atom machine in detail, but if it is a tablet device, the disk is a Flash RAM, which is quite different from the SSD we put into our machines to get rid of spinning HDs ;-)) ?

Perhaps add a storage card used in video cameras ?

If it is a tablet, high probability connection to the server is via WLAN, which is less dependable than wire based stuff, unless you specifically code error handling with temp storage and retry for it.

Printed orders while not all data is in MySQL you have to discuss in a LOUD VOICE with the developer:
topics like transaction, print only if transaction succeeds should echo from the walls while you rub it in ;-)))))
