Frequency isn't the whole story. The CPUs are fast, much faster than a 1.8GHz CPU from a few years back.
 
According to geekbench, the 1.8ghz MBA I just ordered will actually have a better score than the 2.5ghz quad core imac I purchased just last year.

I think it'll be fine.
 
im not really computer knowledgeable so i apologize in advance but I have a netbook with 1.6Ghz and 2gb ram that runs like a snail...I know the ram is little but it starts lagging after 5+ tabs are open which is ridiculous. I know the CPU itself is a new generation, but why is 1.8? How come it cant be 2.4ghz like the MBP? thanks!

That's cause of the new SSD drive vs the HDD inside the iMac though right?

The processor in your netbook is significantly inferior to the Air's processor, so despite the minor numerical difference, there is better performance.

Clock speed has almost nothing to do with processor speed. The 1.8GHz i5 is waaay faster than my 2.4GHz Core2duo. The Macbook Pro processors would take too much power and generate too much heat to work in an Air.
