The trouble is that although the graphics cards they're offering may be decent (although not brilliant: if you had other options would you really want to be editing HD video on a 9600M?) for this year's files and Adobe suite, they may not be much use for the suite that comes out in 2 years or the files we're building then. And if you're spending $2K for a computer, you really don't want to have to replace it every 18 months. Better graphics cards -- at least as *option* -- would make it easier to future-proof your purchase and make it a better value for your dollar.
apple like any other manufacturer wants sales, so it is absolute not in their interest if you keep your Mac for longer then a year , max 2 years , but then you should already have ordered your new one
apple would already rest in piece if they would rely on people like me who are happy with a eMac g4 1.42 , or if i point out your sig on people still using the dual g5 powermac
what i miss at the apple range is something like the dell vostro all in one , a simple AIO with a simple processor (intel pentium dual core ) under 20" that does not look ugly
its not a powerhouse but i do not need one

if it would not be such annoying process to install osx on it i would have done that already and ordered one ,as it costs less then half of a basic imac 21.5 , so i have no choice as i love osx so i will stick with my imac g3's and my eMac , until apple gets it that there not only millionaires out there
