We don't link to Joy of Tech that often, because if we did we'd end up doing it pretty much every day (cue Carly Simon... Noooobody doooes it bettah...). When the readers start giving us the heads-up that Nitrozac and Snaggy have produced something especially trenchant and wry, though, we are bound to take (un)official notice.
Click the image or the Read link for the full comic; it manages to portray the Vista buying experience in very stark contrast to shopping for Our Favorite OS.
Update: Snaggy notes that this cartoon was inspired in part by Erica's post on the multiple versions of Vista. O what a tangled web we weave...
Thanks Ronald & everyone else who sent this in.
