There's some interesting points developing here.

Point 1
Morgan - Are those in the forum representing the 1 percenters out there that are PC geeky ?
I think the proportion of PC users that fall into that category is much higher. In fact I'd say there are two types of users: those that buy PCs to "do stuff" and those that buy PCs to "do stuff for them". The second group don't use their PCs very much in the long term, as they quickly get dissillusioned.Therefore they don't buy much extra software in the long term either. That's not to say they wouldn't buy the Aquarium before the novelty of PC ownership wears off though. That leaves your PC geeky types that like to just "do stuff" because it's there - very geeky, but I think they represent a substantial amount of PC users as the other group keep giving up, to be replaced by next years Christmas Shoppers.

Point 2
Shinsa - the advanced tab - that seems like a really good idea to me, in fact I'd pay extra for it (and I've thought hard about it before saying that!) I think there is a separate market for the two groups of users mentioned above, whereas the original "basic" and "deluxe" versions were targetted at the same people - i.e. the current "basic" version really just entices you to upgrade to more of the same thing (so who wouldn't want it?), whereas a "deluxe" versus "advanced" could be aimed at different user types - Christmas Shoppers versus geeks ! And, as the French would say, Vive La Difference !
