Hey y'all, I should preface this by saying that I know nothing about computers or the finer inner workings that go on inside of them, and a large superficial part of why I want a white Macbook is because "it's just so pretty". That said... what exactly is the difference between Yonah and Merom? A lot of people talk about waiting till Merom and I've even googled it but I'm still not clear. If it's really better to the point that I'll recognize it and somehow affects this heat/mooing issue in some way (don't ask me to explain this connection...I can't) then I want to wait for it... but if it's not going to be horrible earth-shattering... I might have to go for the 1.83, 80GB, 1G Ram, all program pre-installed (Microsoft Office, Firefox/thunderbird, eBrary, Write and Cite etc.) white Macbook my college is selling us for $1387... Right now I'm on a 2-year old Dell that's starting to see the light... and by that I mean it's crawling towards computer death, not that it's getting better. Help?
