I've been trying to find one locally, and of course there are tons of morons on CL jacking up the price trying to resell them for 30% more than retail. It'll probably be weeks before I can find one, which brings me to consider another product.
Samsung Slider Series 7 @ $649.99 USD (Price confirmed by pre-order @ Amazon.com)
Win 7, HDMI out, SD support, physical keyboard, front and rear cameras, (GPRS)3G Support, 2lbs. It makes me consider this now because its coming out VERY soon. The only advantage I like about the ASUS TF is the dock is also a battery in itself, and it runs honeycomb.
