Toshiba Australia release Vista Upgrade prices
Craig Pringle links to a recent addition to Toshiba's support pages, a price-guide for the various upgrades they'll be offering for users currently running Windows XP who'd like to move to Vista on its release. Depending on what current version you're running you'll either pay just shipping and handling or that plus a fee.
Don't forget that these prices are in Australian dollars, not US! There's a list of Vista-compatible notebooks and Tablet PCs on their site too, so you can buy now without the fear that your shiny new toy will be running an old-hat system early next year (subject to Microsoft shipping-slips!)
