i've recently gotten my grubby little hands on an x86 laptop (my brother's old laptop prior to his joining the cult of the mac) - a dell inspiron 2650. so - since i naturally have no intention of letting it retain it's current operating system ... i'm wondering which linux distribution proper geeks run on their laptops these days?

i'm currently thinking either ubuntu hoary (for that comfy old debian feel) or gentoo (which i kinda liked before). anything way better?
