Amazon has a rare discounted Apple MacBook Air on their site, priced at only $1744 after this $50 mail-in rebate. The stunningly 0.76" thin MacBook Air has a 1.6GHz Intel dual-core processor, 2GB memory, 80GB hard drive, wireless networking, a 13.3" display, multi-touch trackpad, built-in iSight webcam, up to five hours of battery life, and Mac OS X 10.5 Leopard. Shipping is free and there's no tax (except KS, ND, WA). Compare this to $1942 after-tax at Apple (assuming an 8% sales tax). When buying, make sure it's on sale explicitly from Amazon (you may have to glance at the seller options listed on the right side of the landing page).
