the fact is it is just waaay too slow at the moment for the average user to bother with DVD ripping. When the average computer is fast enough to do it in real time, maybe, but we are far away from that at the moment (btw, 'average user' doesnt mean 'average Macrumors user').
What, have you ever used Handbrake? My 1-year-old Core Duo MacBook can rip a 1.5-2 hour movie and encode it in MPEG-4 in half an hour flat. That's considerably faster than real time.
We're talking about Apple's slowest notebook over a year and a half ago being able to rip at double/triple-real-time speeds
