Macbook 1.83 vs Macbook 2.0 ghz

[evolution921]

Looking to get either one before Sept to take advantage of the free nano deal. Decided to get laptop because i don't want another desktop as my P4 2.53 still serve me well.

I'm trying to decide if it's worth the $150-200 price diff to get the Macbook 2.0 vs the 1.83. I don't really care about the superdrive since I've only used my dvd burner to burn dvd 5 times max ever since I got it, so for me the only difference would be the 1.83ghz and 2.0 ghz cpu. If I end up getting the 1.83, I may be upgrading the 512mb ram to 1 gig for ~$100.

Any opinion will be appreciated. Main reason I want a mac is to try out the Mac OS, but a window based system will be fine as well, so if you guys have any suggestion for an alternative laptop 13" to 15" weighing ~5 lbs around the macbook price range, that will be great too.

Same performance in my OP. The only difference is the hd size.
