Actually because I'm a student I could get that $2300 iBook for $2150. Always check into educational discounts if you're buying computer stuff. $2150 is still a bit more than I'd like to pay right now though (and I'm not too fond of the non-standard aspect ratio on the tiBooks) . I'm pretty set on the iBook for right now (I might move up to a tiBook in another year or two). As it is right now, I'm thinking I'll get a new one. I would rather a refurbished unit, but the specs on the new ones are the ones I want. Maybe they'll start selling the 800mhz refurbs soon?
However, after thinking about it some more, smp's comments have got me unsure about the 14.1" display. I would like a slimmer, smaller unit, but I just don't know if I can deal with the loss of space (though once upon a time I did use a 14" monitor with a 13.1" viewable area for close to 5 years without problems). I do have a 17" LCD connected to my desktop that I guess I could connect if I wanted to see a bigger picture (I was wanting to leave everything but the ibook home when I went back for the Fall '03 semester though. i'll only be up at school for the one semester then I graduate so I'm planning on packing light. I guess the LCD isn't that big of an item to take).
Basically I think I'm leaning towards the 12.1" screen now, but the 800mhz model (I might get it now or I might wait for the refurbs to show up).
