lol its not about the price... netbooks attract to different consumers
iPhone cannot be compared to a netbook... can you have word on it? no... I agree macbook air serves the function for macs but i do not think air can compete with the netbooks on the market today.
i've had the iPod Touch... and i couldn't stand it... i love macs, i own powerbook g4 12 inch and 17 inch. Obviously the 12 inch is portable enough but people who travel a lot COULD want something lighter and has more battery power... my powerbook is around 5 pounds, just like your MBP... with a brand new battery it runs about 3.5 to 4 hours... just like your MBP. obviously ur machine is stronger than mine... but aside from that, since people who are on the market for netbook are lookng for portability and not as a primary computer are going to care about weight and the battery life.... so its not about the money, its not about your MBP supporting what you need... not about just going on the web with your iPhone.
I jus think people who are loyal to macs want a mac product as an extra. so people who already have a desktop, laptop, could want another mac product that is like a netbook that is lighter with better battery life (current netbooks in the market today like samsun nc10 has up to 7 hours of battery life) for portability. I for one is for apple to come out with a netbook... and i hear they probably will... so im just waiting and seeing whats going on till prob mid summer
