I agree with albrandwood, if I absolutely HAD to pick one of these laptops (based solely on the specs known up to this point), I would go with the Toshiba over the HP because I believe the Intel processor would perform better overall, and the faster hard drive is a must.
In actuality, I would not buy either because they both use shared memory video cards. At the very least, I would pick up the Toshiba and then add on more RAM. With the video card eating up 64MB, that only leaves 192MB for system use. I don't know how much adding the extra RAM would cost, but it would definitely be worth it.
