Both would cost around $1500, with the new I'd get a faster processor and more hard drive capacity, and a free nano/printer. However with the white I'd get a bigger screen, a non-controversial screen, and in my opinion a cuter computer. I just really don't know if it would be stupid to buy "old" technology, instead of getting the newest possible. And if not, why not even buy the white 20" and save $400??!!! To be quite honest, my ibook has 512 RAM and 1.33 Ghz and it suits me fine, speedwise. So I might not even notice the speed difference between the new 20" and old 24". I use mostly Mail, Firefox, Word, Excel, Endnote. A bit of iPhoto and iMovie. Any suggestions/opinions????
