Microsoft last night released the fourth in its series of "Laptop Hunters" commercials taking aim at Mac prices. In the latest commercial, "Sheila" is in search of a laptop suitable for video editing that is within her budget of $2000. Sheila briefly looks at the entry-level MacBook Pro, but finds its 2 GB of RAM unacceptable. She ultimately settles on an HP HDX 16t, an upgraded version of the same notebook selected by Giampaolo in the second installment of the ad campaign.
