Dell sells the Mini 10 in two configurations: one with a 1024 x 600 display ($A649), the other 1366 x 768 ($A749). Both versions include a 250GB hard drive and Windows 7 Starter.
Vodafone's configuration appears to have the lower spec screen, and only includes a 160GB hard drive and Windows XP Home, but does include an internal 3G modem.
Repayments of $A20 per month for 24 months give a hardware price of $A480, so you can forgive the lower specification.
Purchasers have the choice of 3GB or 6GB per month plans, costing $A29.95 or $A39.95 per month (reduced to $A14.97 or $A19.97 for the first six months).
"We are thrilled to be launching the impressive Dell Inspiron Mini 10, and bringing customers a straight-forward, low-cost, fuss-free solution, to enjoy internet on-the-go," said Edward Goff, Vodafone's head of voice and broadband.
