Mac or Dell notebook?

I always have fancied having a Mac Notebook because their design is so sleek, don’t you think ? However I don’t know if Mac memory is as good as the one with Dell. If I were to get a Mac Notebook…I would love to have a pink one *wink*wink*

I won’t be able to compare them myself  since I only had an IBM and a Dell laptop. How about you guys, what do you prefer a Mac or a Dell notebook …and why?
