As reported by Engadget:
In a viral marketing move that's sure to draw the fire of Apple enthusiasts, SanDisk has posted a website called "iDon't" that encourages people to flee the closed iPod universe (the "iTatorship," they call it) -- and to pick up a SanDisk Sansa e200 while they're at it. ... we must say that the iDon't site features little compelling content other than a few cheesy wallpaper downloads and some links to anti-iPod sites, and mostly comes across as sour grapes.
This is malicious marketing. There are no comparisons and no reporting ... and it is all posted by a competitor and meant solely to demean and defame Apple. Seems like it would be an easy lawsuit.
