The macbook is a consumer level computer. It makes no claims to being a gaming computer or a video editing machine. It's designed for people who want to use the internets, email...manage their music, videos, photos, write some papers while listening to music, make stupid faces with the camera and watch dvds while waiting for the plane to start boarding. And the macbook does all these things very well and pleasantly fast, especially with 1GB of memory. It's Mac OS X with more than capable hardware for a reasonable price. And if you want more they have options to upgrade.
As a result of a gamble, I'm currently using a 2001 Powermac g4 running 10.4.9 with a 933 mhz cpu, 133mhz fsb, 1gb of sdram, GeForce 2MX w/32mb GPU. It's crazy loud, power hungry and just an overall eyesore, but it still delivers a damn decent consumer level OS X experience.
Literally days before Apple announced the delay of Leopard, I had just completed the transaction of selling my 9 month old iMac on ebay. The delay of Leopard temporarily screwed my plans up of having a newly designed iMac with Leopard. So now I'll just wait and hope my trusty powermac g4 makes it til christmas.
Bottom line, stop bitching about a great computer, the macbook is great and fast and does what it's advertised to do...if you want higher or "pro" level hardware running OS X you have to get a MBP or Mac Pro.
