actually Gizmo

MOST laptops since pentum3 and the athlons -presant are removable cpu's

BUT!

most are NOT the same socket as their desktop counter parts
AND they are not easy to get to
AND unlike desktops you need a screwdriver to remove the chip... and if you slip you WILL RUIN the mobo *and lappy mobos are VERY pricey*

on desktops it's probally 1/100.000 chance that it's not removable

they are easy to get to/find and easy to remove
