The Palm Treo 680 for Cingular is now free after a $75 mail-in rebate when you buy it along with a service plan at Amazon, despite being $200 at Cingular.com. One of the newer models from the popular PDA & phone family, the Treo 680 is a slightly smaller, updated version of the Treo 650. The 680 offers fast web browsing and email via Cingular's EDGE network, along with a 0.3 megapixel digital camera and bluetooth 1.2. Of note: the newer Treo 750, with a 1.3 megapixel camera and stereo bluetooth, is $149.99 after a $75 mail-in rebate (or $400 at Cingular.com). Two-day shipping is free and there is no sales tax (except KS, ND, WA), unlike your local Cingular store.
