Quote - Twice the lead time? Uh, right. 

In 2001, how many people were using the Internet on a regular basis?

Hmm... How about in 2004?

How about now?

In 2001, how new and fresh (read: exciting) was the whole concept of CG artwork?

In 2008, where almost any movie that wishes to make more than its production cost includes some form of CGI...?

All technical capability questions aside, it's like asking why the Microsoft Zune, a portable music player that's had two years now to get somewhere (and the biggest tech corp on the planet to push it) yet, somehow it can't see fit to break out of last place, let alone take on the iPod in marketshare. Portable music devices are passe' now; they're commodities. You can get one at any price range, with nearly any feature you can imagine. Not much different from 3D/CG apps nowadays, truth be told.

As for the rest? Too much straw in your arguments. The two apps were built for vastly different purposes (as a big ferinstance: one was built as a catch-all suite, the other as a lead-in to content and pricier packages).
