I'm trying to talk my boss into a new laptop... so i'm messing around, spec'ing out the ThinkPad i want. A coworker recently bought a HP laptop that had a 64bit cpu (not sure which one) along with Vista 64. Does Lenovo offer 64 bit cpu's/OS's? I didn't see an option for it on the build i was spec'ing out... but i would venture to think its available somewhere. Am i jsut looking in the wrong place? Oh, i'm interested in the T61 series... none of that tablet stuff for me.
