With respect (seriously), a little bit more...perspective...is in order.
Why does Apple make the MacBook and MacBook Pro? Why not just one model?
Why do they make the Mac Mini and the Mac Pro? Why not just one model?
Why not just offer the iMac instead of the MM and MP since it's all-in-one which is the simplicity and ease of use that are Apple design hallmarks?
Why do they make the iPod Shuffle, the iPod Nano, the iPod Classic, and the iPod Touch? Why not just one model?
Because each device appeals to a different market.
Just because someone does not see a need for it where others do, this does not mean the product itself sucks. It just means it's not for them.
A number of people were arguing for just this form factor and feature-set and if Apple had come out with something bigger and heavier and more capable, they'd be in here bitching about it, instead.
Apple chooses not to please everyone all the time.
If you really want "something for everyone", run Windows on a PC.
