The releases of Windows Vista ("Longhorn") and Firefox 2.0 ("Bon Echo") are slowly creeping up on us, but Microsoft and Mozilla always have their eyes on the next move. Both software makers have chosen codenames for the next-next versions of their flagship products. Microsoft's next version of Windows has been given the codename "Fiji," and Firefox 3.0 will be called "Minefield" (with a cute little logo to match). Why Fiji and Minefield? Who knows. Fiji is short, snappy, and tropical. Minefield, on the other hand, is exciting and aggressive but also kind of worrisome If anything's certain, though, it's that these nicknames will only stick around until the products' final releases, at which point it won't really matter.
